Martina read that approximately 10% of all people are left-handed. She wants to design a

simulation to approximate the probability of selecting exactly 2 right-handed people when 3

people are randomly selected.

Part A

In the simulation, Martina has a spinner with sections of equal size. One section is labeled "L"

(left) and the rest of the sections are labeled "R" (right).

For this simulation to be as accurate as possible, what is the total number of

sections that the spinner should have?
