Concept explainers
In a game, a participant is given three attempts to hit a ball. On each try, she either scores a hit, H, or a miss, M. The game requires that the player must alternate which hand she uses in successive attempts. That is, if she makes her first attempt with her right hand, she must use her left hand for the second attempt and her right hand for the third. Her chance of scoring a hit with her right hand is .7 and with her left hand is .4. Assume that the results of successive attempts are independent and that she wins the game if she scores at least two hits in a row. If she makes her first attempt with her right hand, what is the

- After finishing college. Wally had interviews with SeaWorld and the Central Park Zoo. The probability of receiving an offer from SeaWorld is 35%. The probability of receiving an offer from the Central Park Zoo is 48%. The probability of Wally getting an offer from both SeaWorld and the Central Park Zoo is 15%.Determine the probability of receiving an offer from either SeaWorld or Central Park Zoo but not both.arrow_forwardA market researcher's claim is that women spend more time each day on Facebook than men. If p1 represents the proportion of women on Facebook and p2 represents the proportion of men on Facebook, how would the researcher's claim be represented? a. p1 = p2 b. p1 > p2 c. p1 < p2arrow_forwardMike is planning a vacation. He has narrowed down his choices to three types of vacations: coastal, rural, and urban. He uses the spinner shown above, which is evenly divided into 3 sections, to randomly decide which type of vacation to plan. If he spins the spinner 210 times, predict the number of times the spinner would land on the coastal section. A. The spinner would land on the coastal section roughly 35 times. B. The spinner would land on the coastal section exactly 70 times. C. The spinner would land on the coastal section roughly 28 times, but probably not exactly 28 times. D. The spinner would land on the coastal section roughly 70 times, but probably not exactly 70 times.arrow_forward
