yes, any even number is divisible by 2. the answer to your maths problem is 225
100 to 999 is your range. there are 900 integers in this range. 450 are not divisble by 2 ( the odd ones). 600 are not divisble by 3. half of these are even so only an additional 300 integers are not divisble by 3 alone. so 450 & 300 =750
