The sample space is S = {0, 1, 2, 3, 4). Suppose that Pr({0}) = 0.3, Pr({l}) = 0.2, Pr({2}) = 0.4, and Pr({4}) = 0.1. Find Pr({3}), Pr({1, 2, 3}), and Pr({2, 4}).
For the given sets and sample spaces, show that the assignment of probabilities is mathematically consistent and use them to compute the requested probability.
