Two urns both contain green balls and red balls. Urn one contains 6 green balls and 7 red balls. A ball is drawn from each urn. What is the probability that both balls are red.
Assuming the second urn has an equal number of green and red balls (since that is not specified in the problem), the probability of drawing a red ball from the first urn is 7/13, and the probability of drawing a red ball from the second urn is 1/2.
To find the probability of both events happening (drawing a red ball from each urn), we multiply the probabilities together:
(7/13) x (1/2) = 7/26
Therefore, the probability that both balls are red is 7/26 or approximately 0.269.
