Jenna has a bag that contains 7 red marbles and 25 blue marbles.
She selects a marble at random, and then, without replacing the first one, selects another marble at random.
Let's find out the probability that Jenna selects a blue marble and then a red marble?
=> blue marble probability = 1/32 
=> red marble = 1/31
Round to the nearest percentage = 3%
