There six possible outcomes when a six-sided number cube is rolled. Hence, if we want a 5 as an outcome, the probability of that happening is 1/6.
For the next time it gets rolled, following the same logic, the probability of having 3 as an outcome is 1/6 as well.
Now, if we want to have 5 and 3 as the outcomes for two rolls, it would be equal to (1/6)(1/6).
Answer: D. 1/6 * 1/6
