A candy dish contains 10 red, 10 orange, and 10 black gumdrops. A second dish contains exactly the same assortment. If you select a gumdrop from each dish, what are the chances that you will get two of the same color??

let's do the prob of 2 red

= (10/30)(10/30) = 1/9

the same is true for each of the other two colours

so prob(2 of the same colour) = 3(1/9) = 1/3
