Notation for Probability Distribution of Two Dice Rolls

[Iclaudius]

Hello friends,

I have this problem it reads:

A random variable X is defined to be the larger of the two values when two dice are thrown, or the value if the values are the same. Find the probability distribution for X.

So I don't know how to state "X is defined to be the larger of the two values when two dice are thrown, or the value if the values are the same" mathematically. If someone could tell me, it would be much appreciated.

Thank you for you time,
Claudius

Do you know how to write conditional probabilities?

Lets say your random variable U takes the maximum value of X and Y.

You can write this mathematically as

U = MAX(X,Y), X ~ U(1,6) [Discrete], Y ~ U(1,6) [Discrete].

As for the distribution you can use SW VandeCarr's hint and list conditional probabilities to get a final distribution for U.
