When calculating the probability of x successes in n trials of a binomial experiment, the probability of success and the probability of failure

Multiple choice question.

can both be either negative or positive values, depending on the situation.

remain the same, even when a probability is calculated for a different value of x.

will be less than one when they are summed together.

need to be adjusted when x is zero.

The correct answer is:

- remain the same, even when a probability is calculated for a different value of x.

The correct answer is: need to be adjusted when x is zero.

When calculating the probability of x successes in n trials of a binomial experiment, the probability of success and the probability of failure need to be adjusted when x is zero. This is because when there are zero successes (x = 0), the probability of success is 0 and the probability of failure is 1.
