Lesson 5.3 Checkpoint

When rolling two fair, 6-sided dice, the probability of rolling doubles is 1/6. Suppose that Elias rolls the dice 4 times. Let W = the number of times he rolls doubles.

Determine if this is a binomial setting.

(LT 5.3.1 #1)

• It is a binomial setting

• It is not a binomial setting, because it doesn't have a set number of trials

• It is not a binomial setting, because it doesn't have the same probability for each trial.

• It is not a binomial setting, because it isn't independent

• It is not a binomial setting, because it doesn't have only a success or failure outcome
