A meticulous method to create this would involve partitioning the spinner into 100 segments and coloring 5 of those. This results in a probability of 5/100 = 0.05 = 5%, indicating that each of the 5 segments has a 5% likelihood of being landed upon.

A more efficient approach is to split it into 20 segments instead. This works because simplifying 5/100 yields 1/20 (by dividing both the numerator and denominator by 5). Thus, instead of coloring in 5 segments, Mark should just color 1. If you check this with a calculator, you’ll see that 1/20 = 0.05 = 5% too.

The second choice is more efficient, but a spinner with 20 pieces is still somewhat cumbersome. It may be more practical for Mark to draw random numbers from a hat or use a computer to generate random numbers.
