JJ: I didn't understand what the difference between the probability and odds. In the 2.8 homework the probability was easy but the odds made no sense. How do you change the probability answer to odds?
So I need a little help on finding the odds because it confuses me. Heres an example of what I mean: You toss a six-sided number cube 20 times. For twelve of the tosses the # tossed was three or more. What are the odds that a # is tossed is three or more?
Thx. and yes i realize tht I already did this problem on 2.6 but it IS an odds problem, ok!
I need a little help when it comes to finding the odds when it gives you the probability. EXAMPLE: If i had 5 different color cubes in a hat. What is the probabililty that i will pull a blue? What is the odds?
E.Ma: In this section I thought the probability was easy to find. The part i had trouble with was the odds. I know how to find the odds of rolling a certain number on a die but otherwise I have trouble finding the odds for something else. Can anyone explain to me how to find the odds for anything else?
CT Hey peers! I need help on finding the odds. I have a pretty good idea of how to get it but I'm not really sure on what to do. Here is an example of what I need advice on. If there are 1245 websites on Madison Number One, and 1089 of those sites belong to teachers, what are the odds that the sites are belonging to teachers?
k.a. to jj prob for probability it's for ex.) if you roll a die 1 time the probabilty of getting a 1 is 1/6 chance. for odds you have the # of favorable outcomes (which in this case you want a 1) over the number of unfavorable outcomes (which in this case is 2,3,4,5 and 6) that's only 5 numbers so it's 1/5 odds.
D.M. to J.J. On the 2.8 homework, you had to either find the odds or the probability. to answer, we'll say number 9, you needed to know that there were 220 students. Knowing that, you also know that out of those there were 10 people who said volleyball. With those, you can turn it in to a fraction or ratio, 10:220. Since you have your answer, it would be best if you simplified, 1:22.
On the odd part, numbers 11 and 12, you needed to find out how many were favorable to unfavorable. Example, on 11, you had to find you liked baseball best to the rest of the school. You can subtract the 55 from the 220, you will get 165 students. After that you are able to write your ratio, 55:165. Remember to simplify! 11:33
k.a. to e.ma. k so for anything else you just subract the amount of favorable outcomes from the number of the total amount of outcomes and then you get your unfavorable outcomes then you divide your favorable outcomes by the new unfavorable outcomes and you should have the correct answer.
k.a. to m.g. what you do like if you have 5 dif. colors in a hat and you want to pull a blue that's your favorable outcome and the other 5 colors aren't so it's 1/5. for the probability there's 6 all together (total outcomes) and 1 you want (favorable outcomes) so it's 1/6.
finding the odds that something will happen is putting the favorable outcome over the unfavorable outcomes.
Example There are 1 blue cubes, 1 yellow cube, 3 red cubes and 1 purple cube. You want to know what the odds are of picking the blue cube. You put the favorable outcome (1 blue cube) over the unfavorable outcomes (the total number of cubes minus the 1 blue cube) so the odds that you will pick a blue cube is 1 over 5.
Heya! I need help with finding the odds. I understand what the definition of an odd it but i need help with how to figure it out.
An example of what I need was on last nights homework, 2.8 question #1. I understand how to find the probability but then how do I figure out the odds?
C.T. to E.Ma. Hey peer! I think I found an easier way in finding the odds of an probability. I found that all you need to do to find the odds, was subtract the number of ways you desired by the toal number of outcomes then you get the odds. You would havew to put this into a fraction,so the numerator would be the desired number and the denominator would be when you subtracted the desired amount by the total. For example, what would be the probability be iof you wanted to roll higher than a 2 on a die? What are the odds? Ok. The probability would be 4 out of 6 which is two thirds when you simplified it. OK. To find the odds, like I said, you would subtract the desired amount by the total. You would subtract 6 which was the total by 4 which was the desired, and you get 2. The odds would be 4 out of 2. You would not simplified this fraction. You can use this strategy for finding any odds.
VB to E.Ma: so i'll show u an example with the dice. ok...im gonna give a random prroblem
What is the probability that you will roll a number greater that 2 on a toss of a six sided number cube...what are the odds?
soo. obviously u know wat the probability is...4/6.. and then u can like put the probability into fractiosn, decimals, and percentages if you want. and then the odss. in order to find the odds...u always have to think of this....*the desired outcome out of the total number of outcomes...* the desired outcome in the problem is 4 because u only want a number on the dice that is larger than two. and then the total number of outcomes which is 2.
so the fraction would be 4/2. and then you would simpliy it which would be 2/1 or 2.
but you always have to remember ....*the desired outcome out of the total number of outcomes...*. once u REALLY understand that...finding the odds of a probabiliy will be totally easy

i dont know how to tell apart the odds in a problem from a probabilty. can anyone hep me with this.

k so for anything else you just subract the amount of favorable outcomes from the number of the total amount of outcomes and then you get your unfavorable outcomes then you divide your favorable outcomes by the new unfavorable outcomes and you should have the correct answer.

finding the odds that something will happen is putting the favorable outcome over the unfavorable outcomes.

A.M.
i didnt understand how to write odds. do you write it like likable outcomes over unlikable outcomes or is it likable outcomes over all outcomes?
VB to MG
u shur u haven enuff info so this problem????
