A **Bernoulli trial** is one in which:
AThe outcomes are uncountably many
BThere are exactly two outcomes (success/failure), and probability of success is constant across trials, and trials are independent
CThe probability of success changes between trials
DEach trial has at least three outcomes
Answer & Solution
Correct answer: B. There are exactly two outcomes (success/failure), and probability of success is constant across trials, and trials are independent
Bernoulli trial conditions: (i) exactly two outcomes — success or failure; (ii) probability of success $p$ stays constant; (iii) trials are independent. A sequence of $n$ Bernoulli trials generates a binomial distribution.
