Question

3. In a game, if you roll a 6 on a 6-sided number cube, you lose a turn.

(Part a) What is the probability that you roll a 6? Explain your reasoning.
(Part b) What is the probability that you either roll a 6 or do not roll a 6? Explain your reasoning.
(Part c) What is the probability that you don’t roll a 6? Explain your reasoning.

Answer 1

Part A: The probability is 1/6. This is because there are six options in total, and only one of those options is 6.

Part B: The probability is 6/6, or alternatively 100%. This is because that the probability of rolling a 6 is 1/6, and the probability of rolling any of the other options is 5/6. Adding them together gives a probability of 6/6.

Part C: The probability is 5/6. This is because there are six options, and of those, five of them are not 6.

Answer 2

Part a. 1/6 because there is only one 6 out of 6 in all.

Part b. 1 because the total is always 1 when you add both.

Part c. 5/6 because there is only one 6 and the rest aren't which is 5 out of 6.
