Question 1051311: An NBA player makes a successful free throw 83% of the time. If he takes 7 shots, find the probability that he will make
a) exactly 5 shots
b) at least 6 shots
I wasn't sure how to get started on this problem. I figured I needed to use a tree diagram, but I don't know where to go from there.

You can put this solution on YOUR website! An NBA player makes a successful free throw 83% of the time. If he takes 7 shots, find the probability that he will make
a) exactly 5 shots::: 7C5*0.83^5*0.17^2 = binompdf(7,0.83,5) = 0.2391
b) at least 6 shots::: 1 - binomcdf(7,0.83,5) = 0.6604
