Below for question 10.

Monica [59]

Answer:

3/56

Step-by-step 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 $\frac{1}{8}$ times $\frac{3}{7}$ , which is equal to $\frac{3}{56}$ .

Hope this helps! :D
