Question

A bag contains a red, a green, and a purple marble. In which distributions does the variable X have a binomial distribution? Select each correct answer

Answer 1

There are two answers: B and C

==========================

Explanation:

Replacements must be done so that the probability of getting green (or not getting green) stays the same each time. Choices B and C fit this description.

With any binomial distribution, there are two options. In this case, the two options are "green" vs "not green".

The number of times we select a marble does not determine if we have a binomial distribution or not.
