Question

a blue die and a green die are rolled. find the probability that the blue is 1 or 2 and the green is 1

Answer 1

Assuming the dice are fair, there are 6 numbers.
So now we find the total possibilities that the dice land on 1 or two for the blue and 1 for the green.
2*1 = 2
1 = 1
And then convert these to fractions
2/6
1/6
And then multiply them.
2/36
1/18 is the probability.
