If your teacher asked you to give an example of an event that was most likely to have a probability of 1 from the list

below, which would be the BEST choice?

A - winning a game you played at least twice

B - winning, losing or tying a game you played three times

C - tying a game you played at least five times

D - losing a game you played all your life

B - winning, losing or tying a game you played three times

Explanation:

A probability of 1 means that the event will happen with certainty: there is not other possibility for the event; it cannot not happen; it just happens, no matter what. That is, the probability that it does not happen is zero.

When you play a game you may win, loose or tie. Is there another option? Well, may be not finishing it, but that is not a common situation. That is why is it said, "an event that was most likely to have a probability of 1", and it is not said an event that always has a probability of 1.

With those considerations, the option B - winning, losing or tying a game you played three times is the BEST choice.
