At a certain university in Western Canada, 44% of all 1st-year students are registered in an introductory Calculus course, 26% are registered in an introductory Economics course, and 65% are registered in an introductory Calculus or an introductory Economics course. You randomly pick a 1st-year student from this particular university. Find the probability that the student chosen Part (a) is not registered in either course (use four decimals) Part (b) If a student is registered in introductory Calculus, what is the probability they are also registered in introductory Economics?  (use four decimals) Part (c) iiIf a student is not registered in introductory Economics, what is the probability they are also not registered in introductory Calculus? (use four decimals)
