It is the fault of LaTeX.

Thank you so much, but that answer is incorrect. The correct answer is 17.

Hello Guest! This is a great question!

For the first digit, there are 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

The second digit there are 26 choices, and I am not going to list them all!

The last digit has 10 choices again.

So, in all, there are 2600 possible codes.

For it to contain an odd digit, there are 10 choices for the first or second, and 5 odd choices for the other digit. This makes there be 50 choices with od numbers.

So, here is our answer. The proability is:

50/2600 or 1/52.

I really hope this helped.

You did not miss any! The answer of 16 integers that satisfy n is correct!

Thank you so much!!! 😊😊😊

Thank you so much! So, just to clarify, the numbers under the "n" column are the numbers that satisfy it?

I love puzzles, I am going to try them!

Hello,

Since I have memorized all the presidents, let me say, it was Calvin Coolidge, nicknamed Silent Cal, who hid under his desk to confuse his bodyguards.

He took office upon the death of Warren Gamaliel Harding, who he served as vice president during the term of., and both were Repulican.

How did you solve it?

Thank you, that is correct! BTW, I liked your graphical explantation!

Thank you so much, that is correct!

Hello!

Like with the other question, would you mind making an image so that I can try to solve it? I am not the best at geometry, but I will try to help. Also, I am sure the image will help others who are trying to solve it if I cannot.

Thank you in advance!
