Answer:
B, 1/12
Step-by-step explanation:
The chance of rolling a three on a number cube would be 1/6, because there are six different possibilities that you could roll (1, 2, 3, 4, 5, or a 6) and only one of those possibilities would be a three.
The chance of flipping a coin and getting heads is 1/2, because there are two different possibilities that you could flip (heads or tails) and only one of those possibilities would be heads.

BUT YOU'RE NOT DONE YET!!!</u></h2>
Since it asks for what the probability for doing <u>BOTH</u> of those things, you have to multiply them. Just multiply the numerators and denominators. For 1/6 x 1/2, you'd do 1 x 1 equals 1, so that would be the answer's numerator. Then you'd do 6 x 2, which equals 12, and that would be the answer's denominator. So, putting those two together, you'd get the answer of 1/12.
