Part 1 Casa Loma College offers two types of business programs: a 2-year diploma program (Y2) and a 4-year undergraduate degree program {Y4}. Sixty-ve percent of the students are registered in the 4-year program. Males (M) make up 45% of the students in the 4-year program while 60% of the students in the 2-year program are females (F). (a) Suppose that you randomly select a male student. What is the probability that he is registered in a 2-year program? Part 2 The Mount Pleasant pharmacy chain offers a help line that allows customers to call and receive assistance in solving their prescription issues. However, because of the volume of calls, customers frequently are put on hold. One of the pharmacy claims that 100'!) customers call and among them 400 callers are put on hold. Suppose that 20 customers call. (a) What is the probability that less than four and more than six callers are put on hold? (b) What is the standard deviation of the number of callers that are not put on hold? (c) Now suppose that the same pharmacy above claims that 350 callers are put on hold instead of 400 callers. Find the probability that exactly nine callers are put on hold
