Question

A six-sided number cube is rolled twice. what is the probability that the first roll is an even number and the second roll is a number greater than 4?

Answer 1

Answer

1/6

Explanation

Probability is a chance of an event taking place.

Probability = (favorable outcome)/(total outcome)

There are 3 even sides in a dice.

P(even) = 3/6

           = 1/2

There are 2 numbers that are greater than 4 in a dice.

P(x>4) = 2/6

          = 1/3

P(even and x>4) = 1/2 × 1/3

                           = 1/6
