Question

You roll a fair number cube and flip a coin at the same time. What is the probability that you roll a 5 and flip a heads?

Answer 1

1/12 or 8.3%

Explanation:

To find probability, mark the how many sides you are testing in your probability over the possible outcomes.

Die: 1 side out of 6 sides is the test = 1/6 probability abt. 16%

Coin: 1 side out of 2 sides is the test = 1/2 probability 50%

To find total probability of getting a 5 on the die and a heads on the coin is found by multiplying the two fractions together.

1/6 x 1/2 = 1/12

abt. 16% x 50% = abt. 8%

Answer 2

probably of a head= 1/2

probably of a multiple of 3 (either 3 or 6)= 2ways*1/6 as 1/6 is the prob of any one side
