I'm going to assume that the die has 6 sides and thus has numbers 1 through 6I'm assuming it isn't a 20 sided DnD dice
color is irrelevant, it's used to keep track of which is which
let's say we choose the blue die to get less than 7 and green to get less than 4
blue:all the numbers an a 6 sided die are less than 7, so probility of rolling a number less than 7 on the blue die is 1
green:
3 numbers on a 6 sided die are less than a 46 numbers, 3 to be rolled, 3/6 or 1/2
so probability is 1 times 1/2 or 1/2 or 50% probablity of getting that outcome
