'Bhartdarshan’ is an Internet-based travel agency wherein customers can see videos of the

cities they plan to visit. The number of hits daily is a normally distributed random variable

with a mean of 10,000 and a standard deviation of 2,400.

a. What is the probability of getting more than 12,000 hits?

Answer 1

$P(X>12000)=P(Z>\frac{12000-10000}{2400})=P(Z>0.83)=1-P(Z<0.83)=0.2033.$
