Meet the concept

↗

The indicator of an event E is a Bernoulli variable. Its success probability is equal to the probability of the event E occurring.

Conditions: E is an event in the sample space.; The variable is defined as the indicator of E.

Find a method

For the event E=2,4,6E={2,4,6}, the indicator is one on even die outcomes and zero on {1,3,5}. This creates a Bernoulli variable where success corresponds to rolling an even number.

Conditions: The experiment is rolling a standard six-sided die.; The event E is defined as getting an even number (2, 4, or 6).
