Question

What is not a requirement of the binomial probability​ distribution?

Answer 1

Answer:

B. the trials must be dependent

Step-by-step explanation:

The image for the question is attached.

The missing options are;

A. The probability of a success remains the same in all trials.

B. The trials must be dependent.

C. Each trial must have all outcomes classified into two categories.

D. The procedure has a fixed number of trials.

For a binomial distribution probability, the event must be repeated for a number of time (n) and the probability of success (q) must be the same during each trial.

Binomial distribution probability has two possible outcome: success (p) or failure (q). The event are also independent of each other.

The formula for a binomial distribution probability is given as:

P(X=x) = nCx (p ^ x) (q ^ (n-x))

From the above, we can see that the answer is:

B. the trials must be dependent
