Homework Answers
1. True, because that is exactly what probability of an event tells us.
2. "Realized" is another word used for "Observed". A particular observation is considered to be a particular realization from among many other possible observations.
3. Dependent. Because Dependent is more general notion, independence is a special case of dependence.
4. they are not. Because Mutually exclusive is a very special case of correlation between two events. In general, two events are not mutually exclusive.
5. Multiply the numbers on two corresponding branches. Because
P(A AND B) = P(A B ) = P( B | A)
P(A). So, in tree diagram, P(A) will be written on branch
corresponding to event A, and P(B|A) will be written on branch
corresponding to event B.
6. Sum to 1. Because this is axiom of probability.

Two events, A and B, are mutually exclusive and each has a nonzero probability. If event A is known to occur, the probability of the occurrence of event B is A.One B.Any positive value C.Zero D. Any value between 0 to 1 Suppose that the probability of event A is 0.2 and the probability of event B is 0.4. Also, suppose that the two events are independent. Then P(A∩B) is: a.P(A) = 0.2 b. P(A)/P(B) = 0.2/0.4 = 0.05 c....
