Students can download from http://personal.vu.nl/h.c.tijms/ExamQuestionsUP.pdf a collection of more than 150 probability exam questions with fully worked-out solutions. This set of probability problems accompanies the textbook Understanding Probability of Henk Tijms, but students using another text like Ross or Pitman for their introductory probability course will also find this carefully composed set of exam questions with solutions very helpful and instructive.
