10. Of students ages 16 to 18 with A or B averages who plan to attend college after graduation, 78% cheated to get higher grades (Source: "Who's Who Among American High Schools Students"). Ten randomly chosen students with A or B averages that plan to attend college after graduation were asked, "Did you cheat to get higher grades?". What is the probability that exactly four students answered no? 11. Basketball player Shaquille O'Neal makes a free-throw shot about 65% of the time. Find the probability that the first shot O'Neal makes is the (a) second shot, (b) the first shot, (c) O’Neal does not make the first two shots. 12. A major hurricane is a hurricane with wind speeds of 111 miles per hour or greater. During the 20m century, the mean number of major hurricanes to strike the U.S. mainland per year was about 0.7. Find lambda (^.) for a three-year period. Find the probability that in a three-year period (a) exactly 2 major hurricanes will strike the U.S. mainland, (b) five hurricanes will strike the mainland, and (c) at least 3 hurricanes will strike the U.S. mainland.
