Urn 1 = 1 1 1
Urn 2 = 2 1 1
Urn 3 = 4 5 3
One urn is chosen at random and two balls are drawn they happen to be white and red. What is the Probability that they come from urn 2 & 3?
kindly send me as soon as possible tomorrow my Stats paper

There are some deal-breaker problems with your question. In the first place, you don't identify which column of numbers represents red, which white, and which some unidentified third color. Secondly, you do not make it clear whether the drawing is done with or without replacement. Thirdly, you state that one urn is selected at random and then ask for the probability that the white and red balls come from urn 2 AND 3. Since you only selected one urn, then the balls could not have come from two urns, therefore the probability is zero. But I don't think that is what you meant. I suspect you meant the probability that the balls come from urn 2 OR 3, but in the first place I don't like to base my answers on assumptions made without evidence, and in the second place, answering the question is impossible without the identification of the colors and without specifying with replacement or without replacement.
Revise your submission and repost it. Do not send a clarification to me because I very likely will not be able to help you in time to complete your assignment by the indicated deadline.
