A deck of cards has cards, red cards numbered - and blue cards numbered -

Suppose we shuffle the deck and draw the top two cards. What is the probability that they have the same number?

**I would appreciated if you showed me how you did it!!**

The probability that the first card has a certain number is 2/20. The probability that the second card has the same number is 1/19. Therefore, the probability that the first two cards have the same number is **2/20×1/19 = 1/190**.
