Question

You roll a number cube and flip a coin. What is the probability of rolling an even number and flipping tails? Write your answer as a fraction in simplest form. Example: 1/3

Answer 1

1/4

Explanation:

Doing both of these would be a sequence of events. In order to find the probability of a sequence of events, you need to find the probability of each event happening individually and then multiply them together. A number cube or dice has 6 sides and 3 of them are even numbers meaning that the probability of getting an even number is 3/6 or 1/2 (simplified). A coin only has two sides and 1 is tails so the probability of getting tails is also 1/2. Now we can multiply these two probabilities together.

1/2 * 1/2 = 1/4
