Step-by-step explanation:
A simple event is one that can only happen in one way - in other words, it has a single outcome. If we consider our previous example of tossing a coin: we get one outcome that is a head or a tail. A compound event is more complex than a simple event, as it involves the probability of more than one outcome.
THE CORRECT ANSWER IS A=12 OVER X
The first one is b. The second one is d. Sorry if I’m wrong :(
