Question

(1 point) Consider your Statistics 213 lecture section. There are 120 students registered. Of these 120 students, 52 are Haskayne School of Business students (the remaining students belong to some other faculty). Moreover, 69 students are classified as 1st-Year students and 20 are 1st-Year students and who are not Haskayne students You are to randomly choose one student from the 120 in your lecture section. Let IHS represent the event that the chosen student is a Haskayne-student, and 1st represent the event that this chosen student is a 1st-Year student. Part (a) Complete the table below. Use four decimals in each of your answers

Explanation / Answer

Answer to the question is as follows:

Total students = 120

HSB students = 52

Remaining students of other faculty = 68

1st year = 69

1st year and not HSB = 20

a. P(HS) = HS students/total = 52/120 = .4333

b.P(1st student) = P(1st) = no. of 1st year students/total = 69/120 = .5750

c. P( 1st and HS') = no. of 1st and not HS students/total students = 20/120 = .1667

d. P(HS' | 1st) = no. of non HS 1st year students/total 1st year = 20/69 = .2899

e. P(faculty students) = 1- P(HS) = 1-52/120 = .4250
