Ответ:
The probability that the wait time is greater than 14 minutes is 0.4786.
Step-by-step explanation:
The random variable X is defined as the waiting time to be seated at a restaurant during the evening.
The average waiting time is, β = 19 minutes.
The random variable X follows an Exponential distribution with parameter
.
The probability distribution function of X is:
Compute the value of the event (X > 14) as follows:
Thus, the probability that the wait time is greater than 14 minutes is 0.4786.
