Assume that the normal distribution can be used to approximate the following binomial distribution question. A survey of adults found that 6% say their favorite sport is auto racing. You randomly select 400 adults and ask them to name their favorite sport. Complete parts (a) and (b). (a) Find the probability that the number of people who say auto racing is their favorite sport is at most 30. (b) Find the probability that the number of people who say auto racing is their favorite sport is more than 33. (Round to four decimal places as needed.)
A deck of four (4) cards has exactly one (1) color printed on each face – blue, yellow, red, or green. You have two (2) identical decks of this type. In this game, you randomly select a card from each of the two decks. Your score is the number of blue cards drawn – refer to this quantity as X. The probability distribution is below: X P(X) 0 0.5625 1 0.375 2 0.0625 What is the average number of blue cards drawn? What is the probability that at most one blue card is drawn?

Let X denote the number of winning bids out of the six items you bid on. Find the probabilities. a. Explain why the distribution of X can be modeled by the binomial distribution. b. Find the probability that you win exactly 4 bids. c. Find the probability that you win 4 bids or fewer. d. Find the probability that you win more than 4 bids. a. Explain why the distribution of X can be modeled by the binomial distribution. A. The trials are independent. O B. The data are binary. C. The data are not binary. D. Probabilities of success for trials (bids) differ for each trial. OE. The trials are dependent. F. There is the same probability of success for each trial (bid). G. There are a fixed number of bids. O H. The number of bids varies. b. The probability of winning exactly 4 bids is (Round to four…
78% of U.S. adults think that political correctness is a problem in America today.
