could you anwser this again? your wrong bot
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.
