Question 1083654: Let A be the event that a student is enrolled in an accounting course, and let S be the event that a student is enrolled in a statistics course. It is known that 30% of all students are enrolled in an accounting course and 40% of all students are enrolled in statistics. Included in these numbers are 15% who are enrolled in both statistics and accounting. A student is randomly selected, what is the probability that the student is enrolled in either accounting or statistics or both?

p(A)=0.3
p(S)=0.4
p(Both)=0.15 (that will be subtracted as it is double counting each)
p(A OR S)=p(A)+p(S)-p(Both)=0.3+0.4-0.15=0.55 ANSWER
