Keith's Bakery is giving a treat to each customer at a grand opening event. Each customer spins a wheel to determine which treat they get. Every customer has a 31% chance of getting a macaron, a 48% chance of getting a scone, and a 21% chance of getting a cheesecake.
Keith wants to simulate what could happen for the first ten customers.
So for each customer, he generates a random whole number from 1 to 100.

(a)What is a range of values that Keith can use to represent a customer getting a scone?

(b)Here is Keith's simulation.
Customer 1 2 3 4 5 6 7 8 9 10
Random number 65 70 94 20 46 57 58 9 7 47
Using your answer in part (a), find the percentage of the 10 simulated customers who got a scone.
