Suppose we roll two four-sided dice, that is, each die has 4 sides, numbered 1,2,3,4Let X1 and X2 be the numbers that appear on the first and second die, respectively. LetZ= max(X1, X2), that is Z is the larger of the two numbers rolled.

1)Find the probability mass function,fZ(z), for Z

2)FindFZ(z) =P(Zz) for< z <+.

How do i solve these problems using cumulative distribution function?
