How do I find probability?

Answer 1

SA Given Table, OnCompus job off campus job Not Employed Total – O- 12 hours 13-18 hours is 25 more than 18 hours 23 Tolal 86 So, Total number of students = 86 (i) employed or is taking Probability that a student is between 13-18 hours: P& Employed or laking between 13-18 hours) = Plemployed) + Pleaking between 13-18 hours) + P (Employed and laking between 13-18hours)

43+2o .: Required probability = 35 = 0.81395 43 ł 0.814 (11) Probability that a student is not employed and is laking fewer than 18 hours: - 6+7 = 86 13 86 = 0.15116279 ł 0.1512
