Question

1) Let A be the event that a student is enrolled in an accounting course, and let S be the event that a student is enrolled in a statistics course. It is known that 30% of all students are enrolled in an accounting course and 40% of all students are enrolled in statistics. Included in these numbers are 15% who are enrolled in both statistics and accounting. Find the probability that a student is in accounting and is also in statistics.

2)

A.  Choose from the following: classical, continuous, discrete, Expected Value, independent, Joint Probability, mutually exclusive, P(A and B), Probability, or S = {1, 2, 3, 4, 5, 6}. A.   The general rule of multiplication is used to find the joint probability that two events will occur. Symbolically, the joint probability [___________] is found by: P(A) P(B/A).

3)

Choose from the following: classical, continuous, discrete, Expected Value, independent, Joint Probability, mutually exclusive, P(A and B), Probability, or S = {1, 2, 3, 4, 5, 6}.

Given two events, A and B, if the probability of A is 0.6, the probability of B is 0.4, and the joint probability of A and B is 0.24, then the two events are [______________].

4)

Assigning probability 1/3 of rolling a 4 or 5 on a single die is an example of assigning probabilities using the ________________ method
