Question

The faces of a number cube are numbered 1 through 6. Event A = rolling a 2, 4, or 6. What is the complement of event A?

Answer 1

`{1,3,5}.`

Explanation:

We have, the Sample Space `U={1,2,3,4,5,6}.`

Given the Event `A={2,4,6}.`

Recall that the Complement Event of `A,` denoted by `A'` is

the set of all outcomes not favorable to the occurrence of

`A.`

Clearly, `A'={1,3,5}.`
