determine whether the experiment is a binomial experiment. If it is, identify the values of n, p, q, and x. If it isn’t, state why not. A bag contains 7 red, 5 blue, and 8 purple marbles. You choose 4 marbles from the bag, with replacement. The random variable, x, represents the number of purple marbles obtained.

Yes, n=4, p=8/20=0.4, q=1-0.4=0.6, x=0,1,2,3,4

No, because the selections are not independent.

No, because the probability of selecting a purple marble changes after each draw.

Yes, n=20, p=4/20=0.2, q=0.8, x=0,1,2,3,4

determine whether the experiment is a binomial experiment. If it is, identify the values of n, p, q, and x. If it isn’t, state why not. Bags of Skittles contain 36% red candies. One candy is selected from each of 15 bags. The random variable, x, represents the number of red candies selected.

Yes, n=15, p=0.36, q=1-0.36=0.64, x=0,1,...,15

No, because the probability of selecting a red candy changes with each selection.

No, because the number of trials is not fixed.

Yes, n=36, p=0.15, q=0.85, x=0,1,...,36

determine whether the experiment is a binomial experiment. If it is, identify the values of n, p, q, and x. If it isn’t, state why not. A bag contains 7 red, 5 blue, and 8 purple marbles. You choose 4 marbles from the bag, without replacement. The random variable, x, represents the number of purple marbles obtained.

No, because trials are not independent.

Yes, n = 4, p = 8/20, q = 12/20, x = number of purple marbles.

No, because there are more than two outcomes for each trial.

Yes, n = 4, p = 7/20, q = 13/20, x = number of red marbles.

determine whether the experiment is a binomial experiment. If it is, identify the values of n, p, q, and x. If it isn’t, state why not. A person chooses 6 cards from a standard deck, replacing the card after each choice. The random variable, x, represents the number of diamonds obtained.

Yes, n=6, p=13/52=0.25, q=1-0.25=0.75, x=0,1,2,3,4,5,6

No, because the selections are not independent.

No, because the probability of getting a diamond changes after each draw.

Yes, n=6, p=1/4, q=3/4, x=0,1,2,3,4,5,6
