A computation consists of initialization followed by a WHILE loop. The cost expression of this computation is 10 + 20 e where e is the number of times the true branch of the WHILE statement is executed.

a.)What are the possible values of e?

b.)Select a suitable probability distribution for e.

c.)Assuming that the exit probability from the WHILE loop is 0.4, find the probability distribution of the execution time of this computation using the tabular method (show the first five values in the table).

d.)Use results of c to calculate the probability of C > 40.
