Let A and B be two events. Prove the following:
*P(A intercept B)>= P(A)+P(B)-1
A die is loaded in such a way that the probability of each face turning up is proportional to the number of dots on that face. (For example, a six is three times as probable as a two.) . The die is thrown once.
- What is the probability of getting 1?
- What is the probability of getting an odd number?
You have 2 coins, a fair one with P(H) = ½, and an unfair one with P(H) = 1/3. A coin is selected at random and tossed, falling heads up. How likely that it is the fair one?
