A number cube is rolled three times. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll). The 8 outcomes are listed in the table below. Note that each outcome has the same probability. For each of the three events in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event.

Outcomes Probability
OOO OEO EOO EEO OEE EOE EEE OOE
Event A: Exactly one odd number
Event B: An even number on the first roll
Event C: Alternating even number and odd number (with either coming first)
