Question 121
Multiple Choice
Obtain the probability distribution of the random variable. -When two balanced dice are rolled, 36 equally likely outcomes are possible as shown below. (1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
Let X denote the smaller of the two numbers. If both dice come up the same number, then X equals that common value. Find the probability distribution of X . Leave your probabilities in fraction form.
A) x123456P(X=x) 5/181/47/365/361/91/36
B) x123456P(X=x) 11/361/47/365/361/121/36
C) x123456P(X=x) 5/182/91/61/91/180
D) x123456P(X=x) 1/61/61/61/61/61/6
