Conner took a graphic design class and learned:

Combining red, green, and blue $($RGB$)$ light is the standard method of producing color images on screens. In HTML code, the color red is expressed as a hexadecimal #FF $0000$ or a $24-$bit color depth $($bit is binary digit$),$ which means the browser is showing only red $($FF$)$ with no green $(00)$ and no blue $(00).$

Now Conner got this question on the Liberal Arts Math class:

Q: What is FF equivalent to in Decimals and what is the equivalent in Binary?

He was so confident in his answers since he already knew the letter F is $1111$ from his graphic design class.

Below shows how Conner answered the question, but Conner didn't receive full credit. He argued that he was confident with the solution, and also his numbers were the same as the answer key. $($Answer key: $255$ and $11111111)$
