NAME: 7. (15 points.) Left-handed people are more prone to accident-related injury than right-handed people Among a certain population of college students, the number of injuries X reported by a given student is a Poisson random variable; left-handers (L) report injuries at a handers (R) at a rate of 0.15 per year, 15% of the students are left-handed. rate of 0.25 per year, and right- (a) What is the probability that a randomly selected student is injured exactly twice this...

7. The probability that a randomly chosen student will be left-handed is.09: a) In a class of 108, find the probubility tht there will e(enactly8 lef- handed students b) The classroom has 12 desks designed for people who are left-handed. Use an appropriate approximate method to find the probability that there are enough for all the left-handed students.

Suppose that you are in a class of 32 students and it is assumed that approximately 18% of the population is left-handed. (Give your answers correct to three decimal places.) (a) Compute the probability that exactly five students are left-handed. (b) Compute the probability that at most four students are left-handed. (c) Compute the probability that at least six students are left-handed.
