Consider a barrel containing one copy of each of the 26 letters of the alphabet (A, B, C, …).A. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you replace each letter back in the barrel after you look at it?B. What is the probability of drawing all 26 letters of the alphabet out in exactly alphabeticalorder if you replace each letter back in the barrel after you look at it?C. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you keep the letter out of the barrel after you look at it?

This is not correct. SN1 is not correct. Please double check.
