A bag contains........................the second is white?

Question: A bag contains 4 red, 3 yellow, 3 blue, and 2 white marbles, for a total of 12 marbles. if lucia randomly picks two marbles from the bag without putting the first marble back, what is the probability that the first marble is red and the second is white?

It is the probability that the first marble is red and the second is white that is marbles picked white and third marble red or blue give three ways of getting two white marbles and four ways of getting one red marble and two ways of getting 1 blue marble for the last marble. That give total of three multiply by four plus two is equal to eighteen more ways .
