The answer is 65/126.

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. So, in a bag, there are 36 cards in total. The probability to draw card with a letter is 26 out of 36 or
(26)/(36). After the first draw, there are now 35 cards in the bag. The probability to draw card with a letter now is 25 (since one letter is already out) out of 35 or
(25)/(35).
Since we need for both events to occur, using the multiplication rule, we can calculate the probability that Amy draws two letters:

(26)/(36) ×
(25)/(35) =

(650)/(1260) =
(65)/(126)
