Problem 29
A basketball player makes \(60 \%\) of the free throws that he attempts, except that if he has just tried and missed a free throw then his chances of making a second one go down to only \(30 \%\). Suppose he has just been awarded two free throws. a. Find the probability that he makes both. b. Find the probability that he makes at least one. (A tree diagram could help.)
