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:
- A fixed number of trials.
- Only two possible outcomes for each trial (success or failure).
- Each trial must be independent.
- 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.
