O.K. Here is my question that I am struggling with:
Of all college freshman that try out for the track team, the coach will accept only 30%. If 15 freshman try out for the track team, what is the probability that:
a) all 15 are accepted
b) at least 8 are accepted
c) no more that 4 are accepted
I believe I start the problem like this:
n= 15
p=30
q=1-p=.70
And then we would have:
p(r=15) I know this is wrong but I don't know how to do the part about all 15 being accepted.
p(r>8)
P(r<4)
Don't know wher to go from here. HELP!!!
