or a 
and getting heads on the coin flip?

Answer
Recall what a probability is:
Start by finding the probability of rolling either 
or 
on a die. Since there are a total of 
different outcomes, and we only want these two, the probability must be 
.
Next, find the probability of getting heads on a coin flip. Since we only want heads and there are only 
possible outcomes on a coin flip, the probability of getting heads is 
.
Since the question wants the probability of both events occurring, you must multiply the probabilities together.
