Question 389595: 10.3% of students in statistics actually take the course because they want to. If two students are selected at random, find the probability that both took statistics because they wanted to Answer by ewatrrr(24785) (Show Source):
Hi,
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
10.3% of students in statistics actually take the course because they want to
In this case p = .103 & q = .897
nCx =
P( 2 randomly selected, taking stat because they wanted to) = (.103)^2 = .0106
