In this question, it is said that howard accepted about 9 % of its applicants, stanford 10 % and penn 16%.
00:22
That is, the probability that an applicant can get into harvard is 9 % into stanford is 10 % and into penn is 16%.
00:35
Further, it is said that george has applied to all three.
00:41
Assuming that he is a typical applicant, he figures that his chances of getting into both howard and stanford must be about 0 .9%.
00:55
So in the first question it is asked, how has he arrived at this conclusion? clearly he has multiplied the probability of getting into harvard by the probability of getting into stanford so that this probability is 9 into 10 which is equal to 90 % or in his language it is 0 .9 that is he has multiplied the probabilities of getting into howard and getting into stanford.
02:06
Now in the next question it is asked, what additional assumption is he making? we know that to find the probability of howard intersection stanford, that is, he will get into howard and stanford.
02:27
To find its probability, he multiplied both.
02:32
Both the probabilities, that is probability of getting into harvard and the probability of getting into stanford...
