Answer:
1/8 or 12.5% probability
Explanation:
Compound probability is what you would want to use here which is the probability of the first event multiplied by the second event.
So, if 1/4 is the probability of spinning a 1 on the spinner and 1/2 is the probability of flipping heads, you would multiply 1/4 • 1/2 to get 1/8, or 12.5%
