Question

Can you help me answer this question? (Explain answer please, if you can)

Mr. Perez designs a probability model to help him predict which color car his customers will want to buy. He puts equal numbers of red, black, white, gray and blue slips of paper into a bag to represent all the different possible car colors. Which of the following statements about the model are true?

A. Mr Perez will most likely not pull any black slips.

B. Mr. Perez will more likely to pull a red slip than a blue slip.

C. Adding another white slip would make this a non-uniform probability model.

D. The results of Mr. Perez’s experiment are likely to exactly math the frequency with which his costumers select each color of car.

Answer 1

A. False. Since there are equal numbers of red, black, white, gray, and blue slips of paper, the probability of pulling a black slip is the same as the probability of pulling any other color.

B. False. Since there are equal numbers of red, black, white, gray, and blue slips of paper, the probability of pulling a red slip is the same as the probability of pulling a blue slip.

C. True. If another white slip is added, then the probability of selecting a white car would increase, making the probability model non-uniform.

D. False. While Mr. Perez's probability model may give an indication of which colors are more likely to be chosen by customers, there are many other factors that can influence a customer's choice of car color, such as personal preference, availability, and price. Therefore, the results of Mr. Perez's experiment are unlikely to exactly match the frequency with which his customers select each color of car.
