Answer:
For this case we want to find this probability:
And we can use the cumulative distribution given by:
The mean is given by:
And then
And replacing we got:
Step-by-step explanation:
Previous concepts
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
Solution to the problem
For this case we can define the random variable X= "checkout times"
And the distribution for X is given by:
For this case we want to find this probability:
And we can use the cumulative distribution given by:
The mean is given by:
And then
And replacing we got:
