There are 2 hats. Each hat contains red balls and blue balls. The first hat contains 9875 balls. The second hat contains 11,375 balls. A random sample is chosen from the first hat. This sample contains 56 red balls and 89 blue balls. A random sample is chosen from the second hat. This sample contains 74 red balls and 85 blue balls. At a 1% significance level, use the p-value method to test the claim that the percentage of red balls in the first hat is not equal to the percentage of red balls in the second hat. Please try to show as much work as possible. Thanks.

Question2. An urn initially contains r red balls and b blue balls. In each step, a ball is chosen uniformly at random, and then put back into the urn together with a new ball of the same color. Let Ri be the event that in step i a red ball is chosen from the urn. Show that P(R1 ∩ R2) = P(R2 ∩ R3).

One urn contains 10 red balls and 10 white balls, a second urn contains 8 red balls and 4 white balls, and a third urn contains 5 red balls and 10 white balls. An urn is selected at random, and a ball is chosen from the urn. If the chosen ball is white, what is the probability that it came from the third urn? Justify your answer.

Suppose that: Urn U1 contains 3 blue balls and six red balls, and Urn U2 contains 5 blue ball and 4 red balls Suppose we draw one ball at random from each urn. If the two balls drawn have different colors, what is the probability that the blue ball came from urn U1?

An urn contains five blue, six green and seven red balls. You choose five balls at random from the urn, without replacement (so you do not put a ball back in the urn after you pick it), what is the probability that you chose at least one ball of each color?(Hint: Consider the events: B, G, and R, denoting respectively that there are no blue, no green and no red balls chosen.)
