when a regular 6-sided die is rolled 8 times, x is the number of 4s rolled. does the variable x have a binomial distrubution? if it has a binomial distribution, then give p(success) and the number of trials. if x does not have a binomial distribution, then explainwhy

Answer:

The variable x does have a binomial distribution. A binomial distribution has the following properties:

The experiment consists of n identical trials.

Each trial results in one of the two outcomes: success or failure.

The probability of success, denoted by p, remains constant from trial to trial.

The trials are independent.

In this case:

We have 8 identical trials (rolling a 6-sided die 8 times).

Each trial results in one of two outcomes: rolling a 4 (success) or not rolling a 4 (failure).

The probability of success (rolling a 4) remains constant at 1/6 for each roll.

Each roll of the die is independent of the others.

Therefore, x follows a binomial distribution with:

Number of trials (n) = 8

Probability of success (p) = 1/6
