The probability that a randomly chosen senior among 155 seniors at a local university does not have an internship provided they took an economics class is 8/23 (the answer is given in the simplest fraction form)
No of students who do not have an internship in economics class = 16
Total no. of students in economics class = 46
P(A|B) = probability of occurrence of A given B has already occurred ( conditional probability)
The probability that a randomly chosen senior does not have an internship given that they took an economics class
= P (Does not have internship | Economics class )
= P(Does not have internship in economics class) / P ( Takes economics class )
=16 / 46
= 8 / 23
