1. Say we have four sided dice (sides of 1, 2, 3, and 4, and each side is equally likely). A pair of four sided dice are to be rolled. Let X denote the sum of the two numbers that show up, and let Y denote the absolute value of their difference. a. Compute the joint probability mass function of X and Y, f(x, y)

(23*2)-12=x     x=34

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

i believe it's a.

i'm not sure on this one, most likely correct.
