Question

On St. Patrick's Day, you took note of who was coming into your restaurant wearinggreen. The frequency table shows the results of your survey. What is the probability thata randomly chosen customer will be a female wearing green? Round to the nearestthousandth. males that wore green- 24; males that didn't wear green- 87; total males- 111; females that wore green- 45; females that didn't wear green- 66; total females- 111; total who wore green- 69; total who didn't wear green- 153; total- 222

Answer 1

We have the following table:

g d T

male 24 87 111

female 45 66 111

We will determine the probability that the chosen person is a female that wore green, as follows:

`p=(45)/(111+111)\Rightarrow p=(15)/(74)\Rightarrow p\approx0.203`

From this, we have that the probability to pick a female wearing green at random is approximately 20.270%.
