Answer: The answer is (b) 2.
Step-by-step explanation: We are given to select out of the choices given the number of possible outcomes for one event of a binomial experiment.
A binomial experiment is a statistical experiment having a number of repeated trials where each trial can result in only two possible outcomes. We call one of these outcomes a success and the other, a failure.
For example, tossing of a fair coin is a binomial experiment, because it has only two possible outcomes, head or tail.
Thus, the correct option is (b). 2.
