Question

Which of the following is/are a sure event?

• A. To get a number < 1, when a die is thrown
• B. To get a number $\ge$ 3, when a die is thrown
• C. To get a number $\le$ 4, when a die is thrown
• D. To get a number > 0, when a die is thrown

Answer 1

The correct option is D

To get a number > 0, when a die is thrown

The possible outcomes when a die is thrown are {1, 2, 3, 4, 5, 6}.

Now, to get a number < 1 is not possible. So it is not a sure event.

To get a number $\ge$ 3 is not a sure event. Because there is a chance to get 1 or 2 which are $\ngeqq$ 3.

To get a number $\le$ 4 is also not a sure event. Because there is a chance to get 5 or 6 which are $\nleqq$ 4.

To get a number > 0 is a sure event as all the outcomes are greater than 0.
