Sample Space, Events and Probability
For any event E, we refer to P(E) as the probability of E. Here are some examples. Example 8 Tossing a fair coin. In this case, the probability measure is given by P(H) = P(T) = 1 2. If the coin is not fair, the probability measure will be di erent. Example 9 Tossing a fair die. In this case, the probability measure is given by P(1) = P(2 ...

Even/odd proofs: Practice problems Solutions
faculty.math.illinois.eduSince the sum of two odd numbers is even (by Problem 1), s+t = p2 is even. Hence p, must be even as well (by Problem 2). Therefore p = 2h for some h 2Z, by the de nition of an even integer. 2. Math 347 Worksheet on \Even/odd" Proofs Solutions A.J. Hildebrand
