A die is tossed three times. let X be the sum of the three numbers obtained.

Determine whether the random x has a binomial distribution if so take the number of trials n. If it doesn’t explain why.

Respuesta :

Since for each trial there are more than two outcomes, the random variable x is not a binomial variable.

What is required for a binomial variable?


Three things are required:

  • Each trial has only two possible outcomes.
  • Trials are independent.
  • There is a fixed number of trials.

In this problem, for each trial, there are six possible outcomes for the sum, hence the random variable x is not a binomial variable.
