For example:
If I flip a coin and spin a spinner, whether I flip heads or tails will not effect what I spin on the spinner.
So these are independent events.
An event is considered a simple event when we have only one object in our experiment.
For example:
If I want to know the probability of getting a heads when I toss a coin, I have a simple event.
WHY?
There is only one object - the coin.
An event is considered a compound event when we have more than one object.
For example, if I want to know the probability of tossing a heads on a coin and rolling a 3 on a die,
I have a compound event.
WHY??
There are two objects involved a coin and a die.
Are these events independent?
Yes, because flipping a coin does effect rolling a die.
