Which of the following is the probability of rolling an even number on a 6-sided number cube and flipping a coin twice and getting two heads in a row? 1/2 1/8 1/4 1/3

1/8

Step-by-step explanation:

On a a 6-sided number cube are 3 odd numbers (1, 3, 5) and 3 even numbers (2, 4, 6).

A fair coin has a head and a tail. Probability is the number of possible outcome divided by the number of total outcome.

The probability of rolling an even number is

P(2,4,6) = 3/6 = 1/2

The probability of flipping a coin and getting a head from the flip

= 1/2

As such, the probability of rolling an even number on a 6-sided number cube and flipping a coin twice and getting two heads in a row

P(even number and two heads) = 1/2 × 1/2 × 1/2 = 1/8
