Use the information given in question 48 to find the probability that it will take more than 5 days to find the 11th error. Find the probability that it will take between 3 and 10 days to find the 11th error.

Question 48

A computer programmer has decided to use the exponential distribution to evaluate the reliability of a computer program. After 10 programming errors were found, the time (measured in days) to find the next error was determined to be exponentially distributed with a λ = .25.
(a) Graph this distribution.
(b) Find the mean time required to find the 11th error.
