QUESTION 2 The grades on a test can be A,B,C,D, or F, encoded by the numbers 4,3,2,1 and 0 respectively (so A=4, B=3, and so on). Consider the random variable X = number grade of a student. The following records the number of students with each score: 1 2 3 4 1 3 What is the probability mass function of the random variable X? P(X-k) Please insert in each box above a number in the format 0.xx. (for example, 0.13, or 0.30, etc.)
