Question

Of the 300 employees that were surveyed, 200 had college degrees, 50 were single, and 30 were both single and had college degrees. What is the probability that an employee chosen at random is single or has a college degree?

Answer 1

Single only = 30/300 = 1/10 = .1
Degree only = 200/300 = 2/3 = .67

Either-or probability is found by adding the probability of the individual events.
