A box contains 9 green marbles, 6 blue marbles, and 8 red marbles. Three marbles are selected at random from the box, one at a time, without replacement. Find the probability that the three marbles selected are all different colors.
An urn contains 12 marbles, 31 blue marbles, and 44 yellow marbles. One marble is to be chosen from the urn without looking. What is the probability of choosing a red marble? Your Answer should be rounded to 4 decimal places.
An urn contains 2 red and 2 green marbles. We pick a marble, record its color, and replace it. We repeat this procedure a second and a third time. The probability distribution for the number of red marbles is given below. Number of red marbles 0 1 2 3 Probability 1/8 3/8 3/8 1/8 For this distribution, the probability of exactly one red marble is given by: O 7/8. 113. оо
