Question

In a survey, 100 out of 104 people are not left-handed. What proportion of people are left‑handed according to this survey?

Answer 1

4/104 = 2/52 = 1/26 = .03846154= about 3.8%

unless there are ambidextrous or a-handed people with no hands

which throws off the otherwise binary group into 3 or more non-binary groups

do you count the ambidextrous as 1/2 left and 1/2 right? or zero left? or what if they're 3/4 left and 1/4 right handed? or some other unequal handedness?
