A business is trying to solve a problem by assigning three different employees to work on it independently. Because of experience and skill, the company thinks the probability the first employee solves the problem is 0.6, the probability the second employee solves the problem is 0.6, and the probability that the third employee solves the problem is 0.5. Assuming it is reasonable to believe the success [or failure] of the employees is independent, what is the probability at least one of the three employees will solve the problem?

a. 0.98

b. 1.7

c. 0.18

d. 0.92

e. 0.82

f. None of the above.
