Answer #1
Quality Cost/Convenience Other Total
Full-time 421 393 76 890
Part-time 400 593 46 1039
Total 821 986 122 1829

(a) The probability that they are a full-time student

= Number of full-time students/Total number of students = 890/1829

= 0.4866

(b) The probability that they chose their school for cost/convenience reasons = 986/1829 = 0.5391

(c) The required probability = P(Quality and Full-time)/P(Full-time)

= 421/890 = 0.4730

(d) The required probability = 421/1829 = 0.2302

(e) The required probability = P(cost/convenience) + P(part time) - P(cost/convenience and part time)

= 986/1829 + 1039/1829 - 593/1829

= 1432/1829 = 0.7829

(f) No, the events enrollment status and reason for application are not independent.

Since P(Student chose their school for quality) = 821/1829 = 0.4489 is not equal to the Probability that a student chose their school for quality given that they are a full-time student.
