A baseball player has a batting average of 0.34. What is the probability that he has exactly 6 hits in his next 7 at bats?

The probability is 

PLEASE ADD a full explanation on how to get the answer

Answer 1

binomial formula, given probability of success (p), number of successes (x) and number of trials (n)

p(x = k) = !n

---- p^k * (1-p)^(n-k)

k! (n-k)!

x = number of hits

k = number of successes = 6

p = probability of getting a hit in an at bat = 0.34

n = number of at bits = 7

can use binomial formula to get probability P(x = 6) = 7! (0.34)^6 (0.66) = 0.007

6! 1!
