To find the probability that a randomly selected employee eats breakfast or lunch at the office, we need to calculate the total number of employees who eat breakfast, lunch, or both.
Total number of employees who eat breakfast = 20
Total number of employees who eat lunch = 50
Total number of employees who eat both breakfast and lunch = 15
Total number of employees who eat breakfast, lunch, or both = 20 + 50 - 15 = 55
Therefore, the probability that a randomly selected employee eats breakfast or lunch at the office is 55/80 or 0.6875.
A survey of 80 employees was conducted asking about which meals they regularly eat at the office. twenty employees eat breakfast at the office, 50 eat lunch, and 15 eat both breakfast and lunch. if an employee is randomly selecting an employee who eat breakfast or lunch at the office?
