# Independent Events

How to solve independent events problems (probability): example and its solution.

## Example

In the first selection,

the probability of selecting a gray card is 8/15.

In the second selection,

the probability of selecting a gray card is also 8/15.

The probability didn't change

because of the replacement.

So the first selection

didn't affect the second selection.

Just like this case,

if the first event didn't affect the next event,

then those two events are called independent events.

So the probability is (8/15)⋅(8/15).
