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