Question

the employees of a company were surveyed on questions regarding their educational background ( college degree) and marital status (single or married). Of the 600 employees, 400 had college degrees, 100 were single, and 60 were single college graduates. The probability that an employee of the company is single or has a college degree is?

Answer 1

Number employees N = 600

Then

Probability of Single + College degree = ?

Probability of single S = 100/600 = 1/6

Probability of College graduate G = 400/600 = 2/3

So then probability of both S and G is

Prob Single or Graduate = 1/6 + 2/3 = 1/6 + 4/6 = 5/6

. = 0.833

Then answer is

Probability of Single or Graduate = 5/6= 0.8333

Is also 83.33%
