Step-by-step explanation:
From the question we are told that
The number of success is n = 5
The time duration is N = 125 minutes
Generally the mean of the random variable is mathematically represented as
=>
=>
Generally the rate parameter is mathematically represented as
=>
=>
Generally the cumulative distribution function for exponential distribution function is
Generally the probability that the time to success will be more than 63 minutes is mathematically represented as
Here
=>
=>
So
