An advertising executive receives an average of 10 telephone calls each afternoon between 2 and 4 P.M. The calls occur randomly and independently of one another.
a.) Find the probability that the executive will receive 13 calls between 2 and 4 P.M. on a particular afternoon (solve by hand).
b.) Find the probabily that the executive will receive seven calls between 2 and 3 P.M. on a particular afternoon (solve by hand).
My questions are whether or not this is example of a sampling distribution? And if it is, whats the first step to solving this problem?
