Suppose you were asked to find the probability that it will receive at least three calls, in a given hour: (a) (i) which distribution does this scenario fit and why? (ii) define the variable of interest, X. (iii) what are the possible values of X? (Б) receive at least three calls? What is the probability that in a given hour it willQuestion 4. Consider the probability distribution of X, where X is the number of job applications completed by a college senior through the school's career center. X 1 2 3 4 7 P(X) 0.002 0.011 0.115 0.123 0.144 0.189 0.238 0.178 We collect a random sample of 1000 college seniors who complete job applications through the career center. Part a) Based on the probability distribution, which result would be surprising? 14 seniors completed 1 job application through the career centers. 15 seniors completed 2 job applications through the career center. 130 seniors completed 3 job applications through the career center.For questions 1-2, consider the following scenario: Alice wants to choose constants C and D such that the function Pc.D (x) = De-x+e(1 – Ce-Cx)| is a probability density function.
