Question

Derrick had a 0.250 batting average at the End of his last baseball season witch means that he got a hit 25% of the time he was up to bat if Derrick had 47 hits last season how many times did he bat

Answer 1

`\pprox 12\ bats`

Explanation:

-The probability of success is given as p=0.25

-The number of trials is n=47

-The expected number of hits is obtained by multiply the probability of a successful bat by the number of bats made:

`E(Bat)=np\\\\=0.25* 47\\\\=11.75\approx 12`

Hence, Derrick had approximately 12 bats
