Please Help!!
Suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a red marble followed by a blue marble? Be sure to reduce your answers.
a. 6/81 = 2/27
b. 6/18 = 1/3
c. 5/9
d. 5/18

Best ResponseYou've already chosen the best response.1P(redblue) = (2/9)(3/9) = 6/81 = 2/27

Best ResponseYou've already chosen the best response.0The multiplication rule says we need to find P(red) P(blue). P(red) = 2/9 P(blue) = 3/9 P(redblue) = (2/9)(3/9) = 6/81 = 2/27

Best ResponseYou've already chosen the best response.0Well, you first have to find the chance of getting a red marble, then multiply it by the chance of blue. 2/9*3/9=6/81=2/27
