As in Section 6.6, Exercises 45 and 46, the p.d.f. for the waiting time X until an event occurs often follows the exponential distribution, with the form g(x) = Î»e-Î»x for some positive value of Î», defined for x ‰¥ 0. Use the following indefinite integral fact to find the expectation for the following values of ‰¥.

1. Î» = 0.5.
2. Î» = 2.0.
