A single card is chosen at random from a shuffled standard fifty-two card deck (no jokers). Find the following probabilities:
1) What is the probability that the value 6 shows up on at least on of the rolls?
P(D1=6∪D2=6)

2) What is the probability that the value 6 show up on exactly one of the rolls?
P((D1=6∪D2=6)∖(D1=6∩D2=6))

3) What is the probability (as a rational number is a/b format) that the value sum D1+D2 is 30 ? 10 ? 23 ?
P(D1+D2=30)
P(D1+D2=10)
P(D1+D2=23)

sorry wrong question here the right question : 
A red   20-sided die, with faces marked from   1   to   20 , is rolled.   The result is denoted by   D1 .   Then a green   20-sided die, similarly marked, is rolled.   The result here is denoted by   D2 .
