Given:
A baseball player get a hit in 31% of his at-bats.
To find:
The probability that he will get a hit 5 at-bats in a row.
Solution:
Since, a baseball player get a hit in 31% of his at-bats, therefore
Probability that he get a hit =

=

Now, the probability that he will get a hit 5 at-bats in a row is



Therefore, the required probability is
and it can be written as 0.0028629151 .
