Answer: Let E 1 be the event that the outcome on the die is 5 or 6 and E 2 be the event that the outcome on the die is 1, 2, 3, or 4. In 52 weeks, there are 52 Tuesdays. The sample space of the experiment is, Let A be the event that the coin shows a tail and B be the event that at least one die shows 3. Each student has the same chance to be chosen. Order of a Ratio — the order in which quantities are taken to express their ratio is important. A is on the job for 50% of the time, B is on the job for 30% of the time and C is on the job for 20% of the time.
