Inclusion-Exclusion Principle: an Example

WebFor example, the number of multiples of three below 20 is [19/3] = 6; these are 3, 6, 9, 12, 15, 18. 33 = [999/30] numbers divisible by 30 = 2·3·. According to the Inclusion-Exclusion Principle, the amount of integers below 1000 that could not be prime-looking is. 499 + 333 + 199 - 166 - 99 - 66 + 33 = 733. There are 733 numbers divisible by ...
