A high school baseball player has a 0.274 batting average. In one game, he gets 7 at bats.

What is the probability he will get at least 5 hits in the game?

Calculate the probability of 5, 6, and 7 hits.

 

5 hits

(0.274)^5 * (1-0.274)^2 * 7 choose 5 = 0.017094

 

6 hits

(0.274)^6 * (1-0.274)^1 * 7 choose 6 = 0.002150

 

7 hits

(0.274)^7 = 0.000116, so adding up the probabilities gets us 2.036% as the probability.

 

You are very welcome!

:P
