How many outcomes are possible with bernoulli trial?

The correct answer is A. 2.

A Bernoulli trial is an experiment with only two possible outcomes, usually called “success” and “failure.” For example, flipping a coin has two possible outcomes: heads or tails. Rolling a six-sided die has six possible outcomes: 1, 2, 3, 4, 5, or 6.

In a Bernoulli trial, the probability of success is denoted by $p$ and the probability of failure is denoted by $1-p$. For example, if the probability of flipping a heads is $\frac{1}{2}$, then the probability of flipping a tails is $\frac{1}{2}$.

The number of possible outcomes in a Bernoulli trial is always 2. This is because there are only two possible outcomes: success or failure.
