5. During a tight job market, recruiters have noticed that graduating seniors with an intermediate proficiency in a second language have a higher probability of getting a first interview following a screening call when seeking their first job out of college. For students with one language, the probability of getting a first interview following a screening call is 0.35, whereas for graduating seniors with a second language the probability is 0.45. Let X be the number of screening calls a graduating senior with an intermediate proficiency in a second language must take, up to and including getting their first interview. a) Name a probability distribution that you could use to find probabilities of X. Do not forget to include values of any parameters. b) On average, how many screening calls must a graduating senior with an intermediate proficiency in a second language go through before getting their first interview? c) What is the exact probability that a graduating senior with an intermediate proficiency in a second language must have at least three screening calls to get their first interview? Write down the formula you would use with numbers substituted but use R to calculate the answer. Copy and paste your R code here with the answer from R and summarize the answer in a sentence
