Answer:
Yes, It is a compound event.
Explanation:
Given : Amanda rolls a prime number on a die. She rolls again and gets a 3.
To find : This situation describes a compound event or not?
Solution :
Compound event is defined as an event that has more than one possible outcomes.
Favorable outcomes of getting a prime on a 6-sided die is 2,3,5 i.e. 3 possible outcomes.
Total outcome = 6
When she rolls again she get a 3.
i.e. Probability of getting 3 is

As in a compound event, an experiment gives more than one possible outcomes. These outcomes may have different probabilities but they are all equally possible.
Therefore, The situation given above is a compound event.
