A multinational company has five divisions: A, B, C, D, and E. The percentage of employees from each division who speak at least two languages fluently is shown in Table 8.
Table 8:

(a) Find the probability that an employee selected at random is bilingual.
(b) Find the probability that a bilingual employee selected at random works for division C.
Use Bayes' theorem to calculate the probabilities?

Number of Percentage of Employees Who Are Bilingual Division Employees A 20,000 20 15,000 15 25,000 12 D 30,000 10 10,000 10 Total 100,000
