Question 9 A recruiting firm finds that 20% of the applicants for a particular sales position are fluent in both English and Spanish. Applicants are selected at random from a very large pool and interviewed sequentially. Suppose the first applicant who is fluent in both English and Spanish always gets an offer. Suppose each interview costs $150. Find the expected value of the total interview cost. What distribution do you need to use to solve this problem? O Hypergeometric distribution O Binomial distribution O Negative binomial distribution O Poisson distribuiton
