Question

The life, in years, of a certain type of electrical switch has an exponential distribution with an average life $\beta = 3$. 100 of these switches are installed in different systems, what is the probability that at most 20 will fail during the first year? Click here to see page 2 of the standard normal distribution table. The probability is (Round to four decimal places as needed.)
