A researcher wishes to examine the relationship between wage earned and educational level of workers. For a sample of 4000 workers she has data on hourly earnings (measured in Dollar), age of the worker (in years), worker’s gender, years of experience, number of years with the present employer, size of the firm in which the worker is employed, and highest educational qualification (with 4 classifications: no qualification, secondary school certificate, bachelor degree or PhD)

Here are the projected numbers (in thousands) of earned degrees in a certain country during one academic year, classified by level and by the sex of the degree recipient:
| Bachelor's | Master's | Professional | Doctorate | |
| Female | 932 | 403 | 52 | 28 |
| Male | 663 | 270 | 42 | 28 |
Use these data to answer the following questions.
(a) What is the probability that a randomly chosen degree
recipient is a man? (Round your answer to four decimal
places.)
(b) What is the conditional probability that the person chosen
received a bachelor's degree, given that he is a man? (Round your
answer to four decimal places.)
(c) Use the multiplication rule to find the probability of choosing
a male bachelor's degree recipient. Check your result by finding
this probability directly from the table of counts. (Round your
answer to four decimal places.)
