An urn has 9 balls that are identical except that 6 are white and 3 are red. A sample of 7 is selected randomly without replacement.
What is the probability that exactly 5 are white and 2 are red?


What is the probability that at least 5 of the balls are white?

An urn contains 3 white balls and 7 red balls. A second urn contains 7 white balls and 3 red balls. An urn is selected, and the probability of selecting the first urn is 0.2. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) (a) the probability that the urn selected...

Urn A has 17 white and 4 red balls. Urn B has 9 white and 13 red balls. We flip a fair coin. If the outcome is heads, then a ball from urn A is selected, whereas if the outcome is tails, then a ball from urn B is selected. Suppose that a red ball is selected. What is the probability that the coin landed heads? n

An urn has 12 balls. 8 are white balls and 4 are black balls. If we draw a sample of 3 balls (i.e., picking without replacement) and given that the first two balls selected were a black ball and a white ball, what is the conditional probability of the third ball drawn being white?
