The random variable X is exponentially distributed, where X represents the waiting time to be seated at a restaurant during the evening. If X has an average value of 19 minutes, what is the probability that the wait time is greater than 14 minutes

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.

the answer is d
