Question

Define Sure Event and explain it briefly.

Answer 1

Hint: In order to solve this problem you need to know as the name suggests that it is the event which always happens.

Complete step-by-step answer:

A sure event is the one that contains the whole sample space. A sure event is an event, which always happens. For example, it's a sure event to obtain a number between 1 and 6 when rolling an ordinary die. The probability of a sure event has the value of 1. The probability of an impossible event has the value of 0.

Note: It is the question of the chapter probability. To solve this problem you need to know that sure event is that event which occurs always whenever an experiment is performed. For example, on throwing a die, an event A is defined such that the number appeared is greater than 0. So, the probability of event A is 1.
