Answer:
[tex]\pprox 12\ bats[/tex]
Step-by-step 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:
[tex]E(Bat)=np\\\\=0.25\times 47\\\\=11.75\approx 12[/tex]
Hence, Derrick had approximately 12 bats
