Question 911785
A baseball player has a batting average of 0.395. What is the probability that he has exactly 1 hits in his next 7 at bats?
 What's throwing me off is how the decimal has 3 places. I know the formula is (C n,r) x (p)^r x (q)^n-r
 So my n=7, what am I suppose to do for p and q? 
----
p = 0.395
q = 0.605
