Question

A coin has two sides: heads and tails. A die has six sides, numbered 1 through 6 . If you flip the coin and roll the die, what is the probability that you flip ''heads'' and roll a 4, 5 or

6?

Answer 1

1/4.

Explanation:

Prob (Flipping a Head) = 1/2.

Prob (Rolling a 4,5 or 6) = 3/6 = 1/2.

Prob ( Head then 4,5 or 6) = 1/2 * 1/2 = 1/4.
