One thought on “What is the Probability of an Impossible Event and a Sure Event?”

Arti says:

For example, if a die is rolled, the sample space will be {1, 2, 3, 4, 5, 6} and the event of getting an even number will be {2, 4, 6}. The number of favourable outcomes to the total number of outcomes is defined as the probability of occurrence of any event. A sample space is a collection or a set of possible outcomes of a random experiment while an event is the subset of sample space. The probability of a sure event is always 1 while the probability of an impossible event is always 0. An example of an impossible event will be getting a number greater than 6 when a die is rolled.
