Question

Colorado outfielder Matt Holliday batted .340 in 2007.
What is the probability that Holliday would go 0-for-4 (zero hits in four at-bats) in a game in 2007?
If Holliday had 650 at bats in 2007, what would be his expected number of hits?

(You do not have to answer, I would just like the steps I would take to get the answer, THANKS :) ! )
