An urn contains three red tokens, five blue tokens, and two green tokens.
A green token is drawn from the urn and is not replaced.
A blue token is then drawn from the urn.
--------------
The events are dependent because the green token was not replaced
after it was drawn.
---
P(blue) = 5/10
---
P(blue|green) = 5/9
---
Since P(blue) does not equal P(blue|green) the
events are dependent.
