CEVAP:

A random experiment (trial) with only two possible outcomes is frequently used and called a Bernoulli trial with the following properties:

1. Each trial has only two possible outcomes, such as head and tail, 0 and 1 or success and failure.
2. The trials are independent experiments.
3. The probability of success, denoted by and the probability of failure, denoted by remains constant for all trials (p + q = 1).
