Data for the number of hours needed by sixth grade students to complete a research project is in the table below. Hours: Number of Students: 4 22 5 20 6 30 7 9 8 10 9 7 10+ 6 A student is selected at random. The events A, B, and C are defined as follows. A = the event the student took between 6 and 9 hours inclusive. B = the event the student took at most 7 hours C = the event the student took at least 7 hours Determine each probability. Round values to three places past the decimal. a. P (A or B) = b. P (not C) = c. P (A & C) = d. Determine whether events B and C are mutually exclusive.

Grading One professor grades homework by randomly choosing 5 out of 12 homework problems to grade. (a) How many different groups of 5 problems can be chosen from the 12 problems? (b) Probability Extension Jerry did only 5 problems of one assignment. What is the probability that the problems he did comprised the group that was selected to be graded? (c) Silvia did 7 problems. How many different groups of 5 did she complete? What is the probability that one of the groups of 5 she completed comprised the group selected to be graded?
