Final answer:
To construct a binomial probability, you need to know the total number of trials and the probability of success on each trial.
Step-by-step explanation:
True. To construct a binomial probability, you need to know the total number of trials and the probability of success on each trial. A binomial experiment has a fixed number of trials with only two possible outcomes, such as success and failure. The probability of a success on one trial is denoted by 'p', and the probability of a failure is denoted by 'q'. The mean of the number of successes in the trials is calculated by multiplying the number of trials by the probability of success, while the standard deviation is found by taking the square root of the product of the number of trials, the probability of success, and the probability of failure.
