Each of two urns contains green balls and red balls. Urn I contains 10 green balls and 8 red balls. Urn II contains 3 green balls and 10 red balls. If a ball is drawn from each urn, what is P(red and red)?

The probability of drawing a red ball from Urn I is 8/18 or 4/9.

The probability of drawing a red ball from Urn II is 10/13.
The probability of drawing a red ball from both urns is the product of these probabilities:
P(red and red) = (4/9) x (10/13) = 40/117 or approximately 0.3425.
