A fair die is rolled and the number of dots on the top face is noted. X is the number of times we have to roll in order to have the face of the die show a 2. Does X have a binomial distribution?

Question 8 options:

1) No, because there are more than two possible outcomes for each observation

2) No, because the probability of success for each observation is not the same

3) No, because the observations are not all independent

4) No, because there is not a fixed number of observations

5) Yes, X has a binomial distribution
