P(A) = (380+700)/(2030+890+380+700) = 0.2857 Explanation: We add up the number of employees who are college graduates (380+700) and divide by the total number of employees (2030+890+380+700). P(B) = (890+700)/(2030+890+380+700) = 0.3851 Explanation: We add up the number of employees who make more than $60,000 (890+700) and divide by the total number of employees (2030+890+380+700). P(A ? B) = 700/(2030+890+380+700) = 0.1613 Explanation: We look at the number of employees who are college graduates and make more than $60,000 (700) and divide by the total number of employees (2030+890+380+700). P(B | A) = 700/(380+700) = 0.6486 Explanation: We look at the number of college graduates who make more than $60,000 (700) and divide by the number of college graduates (380+700). P(B | A') = 890/(2030+890-380-700) = 0.5432 Explanation: We look at the number of employees who make more than $60,000 and are not college graduates (890) and divide by the total number of non-college graduates (2030+890-380-700).
