(c) Compute the mean of the number of bullseyes in 10 throws. (d) Find the probability that Slim's first bullseye occurs on the fourth throw. (e) Find the probability that it takes Amarillo more than 2 throws to hit the bullseye. DA (S 4) A dealer in the Sands Casino in Las Vegas selects 40 cards from a standard deck of 52 cards. Let Y be the number of red cards (hearts or diamonds) in the 40 cards selected. Which of the following best describes this setting: coubou (a) Y has a binomial distribution with n=40 observations and probability of success p = 0.5. (b) Y has a binomial distribution with n-40 observations and probability of success p= 0.5, provided the deck is shuffled well. (c) Y has a binomial distribution with n-40 observations and probability of success p = 0.5, provided after selecting a card it is replaced in the deck and the deck is shuffled well before the next card is selected. (d) Y has a normal distribution with mean p= 0.5. 5. Ladies Home Journal magazine reported in 1993 that 66% of all dog owners greet their dog before greeting their spouse or children when they return home at the end of the work day.
