Explanation / Answer

UNABLE TO READ FIRST QUESTION.

2.We have given that n=300 and p=0.7

here np=300*0.7=210>5 and npq=300*0.7*0.3=43>5

we use here Normal approximation

we have to calculate p(X<216)=P(Z<216-210/7.93)=P(Z<0.756)

Using standard normal table

PZ<0.756)=0.7754

Hope this will helps you. Please post remaining question saperately for getting answer

Thanks and God Bless You:).
