A <em>factor</em> is a number that your number is divisible by.

19 has two factors: 19 and 1.
23 also has two factors: 23 and 1.

21 has four factors: It is divisible by 21 and 1, but also by 3 and 7.
25 has three factors: It is divisible by 25, 1, and 5.

We need a number less than 19 that has five or more factors.
What we can do is multiply a bunch of numbers together (so that we know that our number will be divisible by them) to give it a lot of factors.

Let's try 2 × 2 × 3. This gives us 12.

12 has <em>six</em> factors: 12, 1, 2, 6, 3, and 4.

Crank
The percentage change is 6.54%
You have to divide 1800÷1926, then multiply by 100 and you'd get 93.46, then subtract 100-93.46 which equals 6.54% :)

The theorical probability is 1/4, because there are 4 possible outcome, and they are equally likely to be picked (the sectors have the same area)

The experimental probability is 3/20, becuase the red sector was picked 3 times in 20 trials.
