Document Summary

Socsci 2j03 lecture 13 conditional probability and unions. Calculating conditional probability: if a and b are two events, then, Bp: given that p (a ) 0 and p (b ) 0, remember! (multiplication rule for two dependent events, p(a and b) = p(a) x p(b |a) or p(b) x p(a |b) Mutually exclusive events: the joint probability of two mutually exclusive events is always zero. If a and b are two mutually exclusive events, then: p(a and b) = 0. Solution: p (a bar) - the compliment = . 3, solution equation: (tahir, 2019) A university president has proposed that all students must take a course in ethics as a requirement for graduation. Three hundred faculty members and students from this university were asked about their opinion on this issue.
