Step 1 / 6: Defining the Problem

A school principal is purchasing new classroom furniture. Each classroom will have 3030 student desks. There are two types of desks available: standard right-handed desks and universal desks (which accommodate both left- and right-handed students).

Because universal desks cost four times as much as right-handed desks, the principal wants to minimize budget waste. She assumes that, on average, 10%10\% of the student population is left-handed. If we model this situation, the number of left-handed students in a class of 3030 can be treated as a binomial random variable X∼Binomial(n=30,p=0.10)X \sim \text{Binomial}(n=30, p=0.10).
