Hello,

I am in the math challenge II-B combinatorics class. I have a question regarding the week four assignment (on Principle of Inclusion-Exclusion). When the following questions say "between 1 and 100" does it mean inclusive?

F6. How many numbers between 1 and 100 are multiples of either 2, 3, or 5?

F7. How many numbers between 1 and 100 are a multiple of 4, 5, or 6?

P3. How many numbers between 1 - 100 are a multiple of either 5, 7, 9, or 11?

Thank you,

Sophie

Sophie,

Yes, all the questions are meant to be inclusive, so $1$ and $100$ are possible choices.

Best,

John
