Suppose that in a claw game at an arcade, there is a collection of toys that have the following characteristics:

$2/5$ are red;

$3/5$ are waterproof;

$1/2$ are cool.

$($When we write that $2/5$ are red, this means that $3/5$ are not red. But the facts above do not provide any information about the intersection between the different traits.$)$

Furthermore:

$1/5$ are both red and waterproof;

$1/5$ are both red and cool;

$3/10$ are both waterproof and cool.

$($When we write that $1/5$ are both red and waterproof, this contains no information about how cool they are.$)$

Finally, $/10$ are neither red, nor waterproof, nor cool. $($These are pretty lame toys.$)$

Since working those claws is so hard, suppose that any toy in the game has an equal chance of being selected.

The drawing does not need calculations attached to it$.$
