Question

Part B

Historically about 90% of MBAs people who have earned a master's degree in business administration from a ce a un versity n a ob within three months o graduation. Assume for the sake of simplicity that whether a graduate finds a job in three months is independent of whether any of the other graduates find jobs. Complete parts a through c below a. Find the probability that at most 5 (this means 5 or fewer) out of 10 will find a job in their chosen field The probability that 5 or fewer out of 10 will find a job is 0.002 Type an integer or decimal rounded to three decimal places as needed.) b. Find the probability that at least 6 (this means 6 or more) out of 10 will find a job in their chosen field. The probability that 6 or more out of 10 will find a job is (Type an integer or decimal rounded to three decimal places as needed.)

Answer 1

Here we see that p=0.90 is same for all, n=10 is constant, only two outcomes and events are independent

So all the properties of binomial are satisfied

Hence we will use binomial distribution to find

b.
