A bag contains 6 red, 5 blue, and 4 yellow marbles. Two marbles are drawn from the bag, but the first marble drawn is not replaced. What is the probability of selecting a red marble, and then a blue marble?

(p red) = 2/5

(p blue) = 5/14

Step-by-step explanation:

add to number of marbles to get how many are in the bag.

6 + 5 + 4 = 15

Find the probability of drawing a red marble.

(p red) = 6/15

reduce by 3

(p red) = 2/5

The marble isn't replaced, so now there are 14 marbles in the bag. Find the probability of drawing a blue marble.

(p blue) = 5/14

answer: there are 453.592 grams in a pound.
