An amusement park insurance agent wanted to limit the access in the highest roller coaster. No one under 4' 6" (4 feetand 6 inches) in height is allowed to ride. If the average height for visitors is 5' 3" and the standard deviation is 6 inches,what percentage of the population is allowed to ride? Assume that the distribution is normally distributed. A fair die is cast. What is the probability that:Promptsthe result is fourthe result is at most fourthe result is even
