A red in a blue number cube rolled determine that Proability that an odd number is rolled on the Red Cube and a number greater than 1 is rolled on the

6 numbers per cube

3 odd numbers each

so a 3/6 reduced to 1/2 probability of getting an odd number on one

and a 5/6 probability of a getting a number greater than 1 on the other

1/2 x 5/6 = 5/12 probability
