Question

Find P (A^c) P (A^c) =__(Type an integer or simplified fraction.) Find P(A B)=__(Type an integer or simplified fraction.) P(A using the additive rule. Compare your answer to the one you obtained in part b Find P(A Type an integer or simplified fraction.) P(A B)= __ Compare your answer to the one you obtained in part b. Choose the correct answer below. A. Both calculations of P(A produce the same result. The value of P(A calculated using the additive rule is less than P(A calculated by summing the probabilities of the sample points. P(A calculated using the additive rule is greater than P(A union B) calculated by summing the probabilities of the sample points. Are events A and B mutually exclusive? Why? A. Yes, events A and B are mutually exclusive because P(A = 0. No, events A and B are not mutually exclusive because P(A notequalto 0. Yes, events A and B are mutually exclusive because P(A notequalto 0. No, events A and B are not mutually exclusive because P(A = 0. A looked absenteeism, promptness to work, and turnover. The study found that the 60% of the employees had problems with absenteeism, problems with Suppose that 30% of employees had problems with both absenteeism and turnover. Use this information to find the probability that an employee selected from the group surveyed had problems with either absenteeism or turnover. The probability that an employee selected from the group surveyed had problems with either absenteeism or turnover is__.(Do not round.)

Explanation / Answer

5:

Let A shows the event that employee had problems with absenteeism and T shows the event that employee had problem with turnover. So

P(A) = 0.60

P(T) = 0.50

P(A and T) = 0.30

By the addition rule, the required probability

P(A or T) = P(A) + P(T) -P(A and T) = 0.60+0.50 - 0.30 = 0.8
