A group of students were classified based on whether they are senior or junior and whether they are taking CSE446 or not.

Junior Senior
taking CSE446 23 34
no CSE446 41 53

Suppose a student was randomly chosen from the group. Let J be the event that the student is junior, S be the event that the student is senior, C be the event that the student is taking CSE446, and C¯ (C-complement ) be the event that the student is not taking CSE446. Calculate the following probabilities.

(a) (P(C, S)

(b)P(C|S)

(c) P(C complement|J)

There are 120 students registered in a class. Of these 120 students, 52 are Business students (the remaining students belong to some other faculty). Moreover, 71 students are classified as 1st-Year students and 20 are 1st-Year students and who are not Business students. You are to randomly choose one student from the 120 in your lecture section. Let HS represent the event that the chosen student is a Business-student, and 1st represent the event that this chosen student is a...
