Poisson distribution
1. The number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM has a probability distribution with a mean of 4.
Answers
Let X be the number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM. Clearly X is Poisson with mean = 4. The probability density function of Poisson random variable is given by The probabilities for different values of X are given ...
