I'd say that me drawing a red one is 1 in 3, and you drawing a red one is
one in 3

so the chances are for us to draw a red at the same time is 1 in 9.

The chances to draw a blue one at the same time is 1 in 9

the chances to draw a white one at the same time is 1 in 9

So again, my bad math, I'd say the chances for us to draw the same colour is
3 in 9, or 33 percent.
