Write out all the numbers between 1 and 25 that are divisible by either 3 or 7. Count how many there are. Divide that number by 25. Viola!

A number divisible by 3 is = 3, 6, 9, 12, 15, 18, 21, 24
= total 8 numbers.
A number divisible by 7 is = 7, 14, 21
= total 3 numbers.
A number divisible by 3 is = 3, 6, 9, 12, 15, 18, 21, 24
= total 8 numbers.
A number divisible by 7 is = 7, 14, 21
= total 3 numbers.
Shyam, if you are going to simply handout complete solutions at least do them correctly.

Jhevon made the same mistake !
It's voilą
Viol...means rape ! but don't worry, I would give my consent xD
The viola is my favourite instrument. I like to hear it sometimes when I post. Hence my deliberate transposition of letters. As for Jhevon, I think he's just lousy at French
