Approximately 10% of all people are left-handed. If 200 people are randomly selected, what is the expected number of left-handed people? Round to the whole number. Do not use decimals. Answer:

N (L) = 20

The expected number of left handed people is 20.

Step-by-step explanation:

Given;

Percentage of left handed people P (L) = 10%

Total number of selected people N (T) = 200

The Expected number of left handed people N (L) is;

N (L) = Total number of selected people * Percentage of left handed people/100%

N (L) = N (T) * P (L) / 100%

Substituting the given values;

N (L) = 200 * 10%/100%

N (L) = 200 * 0.1

N (L) = 20

The expected number of left handed people is 20.
