Given : The length of a telephone conversation in a BOOTH has been an exponential DISTRIBUTION and found on an average to be 5 minutes.

Step-by-step explanation:

Mean = 5 mins

=> λ = 1/5

The cumulative distribution function is given by

= 1 - $e^{- \lambda x }$

λ = 1/5 x = 4 minutes

= 1 - $e^{- \frac{4}{5} }$

= 1 - 0.449

= 0.551

0.551 is the Probability that a random call made from this booth

ends less than 4 minutes
