1.A spinner has five equal sections that are numbered 1 through 5.

In which distributions does the variable X have a binomial distribution?

Select each correct answer. (pick more than 1)

When the spinner is spun five times, X is the number of times the spinner lands on 1.

When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.

When the spinner is spun three times, X is the sum of the numbers the spinner lands on.

When the spinner is spun multiple times, X is the number of spins until it lands on 5.

1) 1 and 2 are binomial distributions

 

3) 1 and 2 are likely to be approximately normally distributed.

Only approximately though as neither ages nor heights can be negative.

The normal distribution, regardless of the mean and variance, has non-zero probability of negative numbers.
