There are two urns: urn A and urn B. Each urn contains only red
balls and blue balls.It is known that urn A has 14 red balls and 11
blue balls, while urn B has a total number of 23 balls.
In a random experiment, an urn is first randomly chosen and then
2 balls are drawn without replacement from the chosen urn. Suppose
that the probability of choosing urn A and the probability of
choosing urn B are both positive.Can the events"the two chosen
balls are red' and"urn A is chosen" be independent?
