so there is 10 possible shot, he will make 9

probability of him making shot  is p=.75

   (10 p 9)(.75)^n(.25)^(10-n)

anonymous · Answer

would you mind showing me or explaining the first parenthesis? (10p9)? is this just a lable

so how many ways can you get 9 out of 10 shot

s=shot
m=missed

s s s s s s s s s s m

s s s s s s s s s m s

s s s s s s s s m s s
