At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 8 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color?

8 over 32 multiplied by 8 over 31
8 over 32 plus 8 over 31
8 over 32 plus 7 over 31
8 over 32 multiplied by 7 over 31
