Best ResponseYou've already chosen the best response.1to find the probability of your case, you need to compute the prob P(exactly one can is cola) + P(exactly two cans are cola) + P(all three cans are cola) but tat will take a while so we use another technique

Best ResponseYou've already chosen the best response.1anyway, the complement of (at least one cola) is (no cola at all) and the probability of a complement is p(complement) = 1p(statement) so 1p(no cola) would be easier to calculate

Best ResponseYou've already chosen the best response.1can you find the probability that the two cans you pulled out contains no cola can ?

Best ResponseYou've already chosen the best response.1okay so since you are pulling out two cans from a container at random without any replacement, the the way you pull out two cans will have these following steps 1), pull out a can from 7 cans 2), pull out another from the "remaining 6" so, try to answer step 1). what is the probability of pulling out a noncola can out of 7 ?

Best ResponseYou've already chosen the best response.1that is not right you have 4 cans that ar noncola out of 7 so ...

Best ResponseYou've already chosen the best response.1now, how many noncola cans are there in the container left ?

Best ResponseYou've already chosen the best response.0First draw 3/7 probability for a cola second draw 3/6 probality for a cola probability from both draws getting at least on cola is 92% Doesn't seem right.

Best ResponseYou've already chosen the best response.1nope initially you had 4 noncola cans right ? are you having trouble identifying what a noncola can is ? Cherry and Orange are the noncola cans. we had 1 cherry and 3 oranges , 4 total. since we pulled out one , so how many should be left ?

Best ResponseYou've already chosen the best response.1exactly, so now you are ready to answer step 2) what is the probability that you can pull out the 3 noncola cans from the remaining 6 ?

Best ResponseYou've already chosen the best response.1you are only two steps before the answer ok? so what was the prob of 3 cans out of 6 ?

Yuki

Best ResponseYou've already chosen the best response.1the last step is to multiply those two probabilities, 4/7 * 3/6 = ?

Best ResponseYou've already chosen the best response.1haha you can just use fractions you know, 2/7 anyways, remember that we were looking for the complement ? all you have to do now is to subtract this from 1. so the answer is 1  2/7 = ?

Best ResponseYou've already chosen the best response.1Now if you really seek help, I recommend you to hire a private tutor or go to a tutoring center or an after school program. the type of help you need is not easy to obtain online and as you noticed, it takes a bit while to solve just one problem. I will be more than happy to help you but you need to relax and get help efficiently, ok? Now good luck. :)

Best ResponseYou've already chosen the best response.0P(there is no cola)=7/10*6/9=21/45 P(there is a least 1 cola)=1P(there is no cola)=121/45=24/45
