The faces of a fair cube are numbered 1 through 6; the probability of rolling any number from 1 through 6 is equally likely. If the cube is rolled twice, what is the probability that an even number will appear on the top face in the first roll or that the number 1 will appear on the top face in the second roll?

1/12

Probability of an even number

1/6

Probably of even number on first try and 1 on second try

1/2 * 1/6 = 1/12
