Everything else the same, if the yield curve is downward sloping, what is the yield to maturity on a 10-year treasury coupon bond, relative to that on a one-year treasury bond (t-bond)?

Step-by-step explanation:

Given : A building security code has 2 numeric digits 0 through 9 followed by 2 letters.

Total digits (0,1,2,3,4,5,6,7,8,9)= 10

Total letters in English Alphabet = 26

Then, the total number of ways to make a code if repetition is allowed :-

The number of ways to make a code with first digit is nine an last letter is A (we fix first position for 9 as 1 and the last position for a as 1) , if repetition is allowed :-

Then, the probability that the first digit is nine an last letter is A :-

Hence, the probability that the first digit is nine an last letter is A=
