Answer 1

No, The event B is not a simple event because event B has more than one outcome.

Explanation:

Consider the provided information.

A computer is used to select randomly a number between 1 and 9 comma inclusive.

Event B is selecting a number greater than 4.

Let B be an event that the selected number greater than 4.

We have given that the total number used by the computer is:

1, 2, 3, 4, 5, 6, 7, 8, 9

Now the sample space for selecting a number greater than 4 is:

S = {5, 6, 7, 8, 9}

Therefore, the event B has 5 outcomes.

The event B is not a simple event because event B has more than one outcome.
