In a game, you have found a reward with 15 treasure boxes. From experience youknow that 1 in 5 treasure boxes contain rare items.a. You want to know the probability of having 4 rare items in your 15 treasure boxes.Can the normal approximation to the binomial distribution be used? Justify youranswer and describe why it is important to check that the normal approximation canbe used. (b. If you instead had 50 treasure boxes, could the normal approximation to thebinomial distribution be used?

a. To determine if the normal approximation to the binomial distribution can be used, we need to…

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities.What's your favorite ice cream flavor? For people who buy ice cream, the all-time favorite is still vanilla. About 26% of ice cream sales are vanilla. Chocolate accounts for only 10% of ice cream sales. Suppose that 168 customers go to a grocery store in Cheyenne, Wyoming, today to buy ice cream. (Round your answers to four decimal places.) (a) What is the probability that 50 or more will buy vanilla?(b) What is the probability that 12 or more will buy chocolate?(c) A customer who buys ice cream is not limited to one container or one flavor. What is the probability that someone who is buying ice cream will buy chocolate or vanilla? Hint: Chocolate flavor and vanilla flavor are not mutually exclusive events. Assume that the choice to buy one flavor is independent of the choice to buy another flavor. Then use…
