Best ResponseYou've already chosen the best response.0the probability of having a girl is 1/2. so the probability of having a boy is 1/2. in a family of 5 children, all are boys. i.e, there are no girls. so the parents had five boys consecutively. so the probability of having 5 boys in a row is 1/2 times 1/2 times 1/2 times 1/2 times 1/2

Best ResponseYou've already chosen the best response.0okay very good. now you have 6 cherry, 3 lemon and 2 grape candies. what is the probability that you pick one cherry candy?

Best ResponseYou've already chosen the best response.0okay very good. now, you have already picked one candy. so there are ten candies left. 5 cherry, 3 lemon and 2 grape. what is the probability that you pick a cherry candy?

Best ResponseYou've already chosen the best response.0yes, good. now there are 9 candies left. 4 cherry, 3 lemon and 2 grape. what is the probability that you pick a lemon candy?

Best ResponseYou've already chosen the best response.03/9, and then you multiply right? thats how i tried to solve the original one but i got the wrong answer

Best ResponseYou've already chosen the best response.0yes, so the probability that you pick 2 cherry candies in a row and then one lemon candy is 6/11 times 1/2 times 1/3.

Best ResponseYou've already chosen the best response.0for 6 cherry, 3 orange, and 2 lemon; the prob of 2 cherry and 1 lemon: answer is supposed to be .1818

Best ResponseYou've already chosen the best response.0the question says there are only 2 lemon candies and there are 3 orange candies. so for the third try, you pick a lemon candy out of 9 candies, the probability of that is 2/9 so the answer should be 6/11 times 1/2 times 2/9

Best ResponseYou've already chosen the best response.0yeah i can do that and get .0606; but the book says the answer is supposed to be .1818

Best ResponseYou've already chosen the best response.0wait, is that supposed to be in that order?

anonymous

Best ResponseYou've already chosen the best response.0yeah it says random, but is the expected answer 1 cherry then 1 cherry then 1 lemon or is it that you pick three candies and you end up with 2 cherries and 1 lemon?

Best ResponseYou've already chosen the best response.0okay looks like you are not reaching in three times. you just reach in once and take three candies.

Best ResponseYou've already chosen the best response.0it says "you reach in and take 3 pieces of candy at random"

Best ResponseYou've already chosen the best response.0do you know how to figure it out that way?

anonymous

Best ResponseYou've already chosen the best response.0yeah. you have to do it the following way: 6C2/11C3 times 2C1/11C3

Best ResponseYou've already chosen the best response.0have you done permutations and combinations? BTW ignore my answer. that is incorrect. I will calculate the correct answer and post it here.

Best ResponseYou've already chosen the best response.0my teacher gave us problems to do but never taught us how, but yes we are supposed to be doing permutations and combinations. any quick formulas i can jot down for the test?

anonymous

Best ResponseYou've already chosen the best response.0The answer is 6C2 times 2C1 divided by 11C3

Best ResponseYou've already chosen the best response.0so that is 15 times 2 divided by 165 = 30/165 = 0.181818181
