Primes, Multiples & AC
- What it is
- How many drawn numbers are prime, multiples of three or composite, and the AC value of each draw.
- How it is calculated
- A prime has exactly two divisors (2, 3, 5, 7 ...). Composites are non-prime numbers above 1. AC (arithmetic complexity) is the number of distinct differences between all pairs of numbers, minus 4; it runs from 0 to 6 for five numbers.
- How to read it
- These are other ways to group numbers. Compare averages with what you would expect given how many numbers of each type exist.
- What it can't tell you
- These groupings have no connection to how the balls are drawn.
- Common misunderstanding
- 'Prime numbers are luckier.' The drawing machine does not know what a prime is.
