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)

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
