Math Problem Statement

Determine whether the given procedure results in a binomial distribution. If not, state the reason why. Rolling a single die 26 times, keeping track of the numbers that are rolled. Not binomial: there are too many trials. Not binomial: the trials are not independent. The procedure results in a binomial distribution. Not binomial: there are more than two outcomes for each trial.

Solution

The procedure described — rolling a single die 26 times and keeping track of the numbers that are rolled — does not result in a binomial distribution because there are more than two possible outcomes for each trial.

Explanation:

A binomial distribution requires:

  1. A fixed number of trials.
  2. Only two possible outcomes for each trial (success or failure).
  3. Each trial must be independent.
  4. The probability of success is the same for each trial.

In this case:

  • Rolling a die has 6 possible outcomes (numbers 1 through 6), not just two.
  • Thus, it violates the requirement of having only two outcomes per trial, so the distribution cannot be binomial.

Conclusion:

The correct answer is: Not binomial: there are more than two outcomes for each trial.
