    Gamma distribution

    The CPU requirement of a typical program measured in minutes is found to follow a Gamma (r = 3, λ = 1/2) distribution. What is the probability that the CPU demand of a program will exceed 1 min?

    Calculate \int_1^{+ \infty} f(x) \, dx or perhaps easier, calculate 1 - \int_0^1 f(x) \, dx.
