A customer service representative must spend different amounts of time with each customer to resolve various concerns. The amount of time spent with each customer can be modeled by the following distribution: X ~ Exp(0.4). Find P(1 < x < 18). (Round your answer to four decimal places.)

0.02040816326

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

now you divide like you would normally would and get 0.0076

5 + 8 +7 + 4 + 0 +1 = 25
