Academicians was surveyed of their loyalty to the university. They're asked “If given an offer by other university equivalent or slightly better than present position, would you remain or not?Table 4 represents the responses of the 200 academicians which were cross-classified with their length of service.
Table 4: Loyalty of Academicians & Length of Service.
Length of Service Total
Loyalty Less than1 yr, 1-5 yr, 6-10 yr, More than 10 yr
Remain 10 30 5 75 120
Not remain 25 15 10 30 80
a)represent the information in Table 4 as a tree diagram.
b)What's the probability of randomly who is loyal and who has more than 10 yr service?
c)What's the probability of who would not remain and has less than 1-yr of service?
d)What's the probability of who would remain, given that he or she has 1-5 yr of service?
e)What's the probability of who would not remain, given that he or she 6-10 yr of service?
