For this problem let the sample space be S = {1,2,3,4,5,6,7,8,9} and suppose all the outcomes are equally likely. What is the probability of event E = "an odd number"? (no work is needed)
- If two events are defined as: A = {4, 5, 6, 7}, and B ={7,8,9} then find P(A or B). Also comment on whether A and B are mutually exclusive and tell why or why not.
