We are told that bag B contains red and white marbles in the ration 1:4. This implies that WB, the number of white marbles in bag B, must be a multiple of 4. Thus, the number of red marbles in bag A is either 2 or 6. Only one answer choice matches either of these numbers.
An experiment consists of drawing a marble, replacing it, and drawing another marble. The two draws are independent. A random variable assigns the number of blue marbles to each outcome.What is the probability that the random variable has an outcome of 3?
A bag of marbles contains 3 green, 6 red, 6 blue, and 1 yellow marble. If Juan randomly selects two marbles to use for a game, what is the probability that both marbles are blue?

Jan 07, 2017 · A bag contains 3 red marbles and 4 blue marbles. a marble is taken at random and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the bag are the same color. Total number of marbles in the bag is 3 + 4 = 7.
Example: there are 5 marbles in a bag: 4 are blue, and 1 is red. What is the probability that a blue marble gets picked? Number of ways it can happen: 4 (there are 4 blues) Total number of outcomes: 5 (there are 5 marbles in total) So the probability = 4 5 = 0.8
