PLEASE HELP: Which is a compound event?

The correct option is;

Heads lands 3 times and tales lands 5 times in 8 coin flips

Step-by-step explanation:

A compound event is one in which the probability of more than one outcome or event to have occurred at the same time is sought. The probability of a compound event is the sum of the probabilities of the individual events less the probabilities already captured in both event probabilities

Answering compound event questions can be done by the use of a tabular or diagram format.

Therefore, the compound event in the list is heads lands 3 times and tales lands 5 times in 8 coin flips.
