12.5% is simply a part of the fraction which has the same shape or portion on the fraction pie.

To find out how often you can expect to get a number evenly divisible by 2 in 20 spins, you need to determine the probability of getting such a number on a single spin.

Since half of the numbers on a standard roulette wheel are even (1, 3, 5, etc.), the probability of getting an even number on a single spin is 1/2 or 0.5.

To calculate the expected number of times you'll get an even number in 20 spins, you can multiply the probability of getting an even number on a single spin by the number of spins.

Expected number = Probability of event * Number of trials

Expected number = 0.5 * 20
Expected number = 10

Therefore, you can expect to get a number evenly divisible by 2 approximately 10 times in 20 spins.
