Answer:

3/56

Explanation:

There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to
(1)/(8) times
(3)/(7), which is equal to
(3)/(56).

Hope this helps! :D
