If events A and B are independent, then the probability of simultaneous occurrence of event A and event B can be found with ____________. P(A)·P(B) P(A)·P(B|A) P(B)·P(A|B) All of these choices are correct.

1. If two events are independent how do we calculate the and probability, P(E and F), of the two events? (As a side note: this "and" probability, P(E and F), is called the joint probability of Events E and F. Likewise, the probability of an individual event, like P(E), is called the marginal probability of Event E.) 2. One way to interpret conditional probability is that the sample space for the conditional probability is the "conditioning" event. If Event A...

13.If two events A and B are statistically independent, then: a. A's occurrence makes it less likely that B will occur. b. A's occurrence makes it more likely that B will occur c. A's occurrence makes it impossible that B will occur d. A's occurrence has no effect on the probability of B occurring. e. B's occurrence has minimal effect on the probability of A occurring 14.If two events are independent, then: a. they must be mutually exclusive b. the...
