To find: The most likely number of hits.
4 hits.
Given:
A softball player gets a hit in about 31% of her at-bats.
15 players are randomly selected at-bats.
Calculation:
Here, the probability of success is
The probability of failure is,
Let
Then,
Now,
Clearly, the probability of hitting 4 hits is maximum.
Therefore, the most likely number of hits the player will have in 15 at-bats is 4 hits.
