The probability of drawing a red ball from urn one is 4/10 or 2/5. The probability of drawing a red ball from urn two is 7/15. The probability of both events happening together is found by multiplying the two probabilities:
(2/5) x (7/15) = 14/75
Therefore, the probability that both balls drawn are red is 14/75.
Two urns both contain green balls and red balls. Urn one contains 6 green and 4 red balls and urn two contains 8 green balls and 7 red balls. A ball is drawn from each urn.
What is the probability that both balls are red.
