Question

Derek has a white cube and a red cube.

The numbers 1 to 6 are on the cubes. If
Derek tosses the cubes at the same time,
what is the probability he will get a 4 on
the white cube and a number greater than
4 on the red cube?

Answer 1

1/72

Explanation:

Probability of getting a 4 on white cube is:

P(W) · P(4) = 1/2 × 1/6 = 1/12

P(R) · P(>4) = 1/2 × 2/6 = 1/6

multiply both probabilities: 1/12 × 1/6 = 1/72
