A jar contains 28 marbles. Half of the marbles are red. Half of the non-red marbles are white and the rest are blue. Todd chose a white marble at random and kept it. What is the probability that when Hosea now draws a marble it will also be white? Express your answer as a common fraction.

.5 chance for red b/c it is half

 

.25 for white and blue but...

 

1 white is taken out so the jar is 27/28

 

28/4 = 6

12 is red 

6 are blue/white

that means 5 whites are left

5/28 chance for white
