Probability models, random variables with discrete and continuous distributions. Independence, joint distributions, conditional distributions. Expectations, functions of random variables, central limit theorem. Prerequisite: MATH 22, 112L, 122, 122L, 202, 212, 222, OR Graduate Student; NOT open to students who have credit for Mathematics 340.
Math 230 is usually offered in Fall, Spring, and at least one Summer term.
Enrollment in Math 230 requires credit for second semester calculus (Math 22, 112L, 122L, or 122) on your Duke transcript.
If you have AP or international placement exam scores that you expect to result in AP or IPC credit for Math 22 but have not reported the scores yet, you should do that ASAP to result in the Math 22 credit needed for enrollment in this course. If you have taken a second-semester calculus course that you hope will result in PMC or transfer credit for Math 122, you should likewise begin that process ASAP.
If you have a very strong background in second semester calculus that you feel is equivalent to the level of our Math 122L, but do not have such credit on your Duke transcript, and if you would like to be considered for an exemption from the second semester calculus prerequisite, you may take our "Math 122L Proficiency Exam"; students who do well on this exam will be granted permission to enroll in Math 230, at the discretion of the Supervisor of First-Year Instruction.
This exam is offered each semester shortly before the first day of classes. Click here to REGISTER for this exam; date/time details will be sent to registered students by email. Students registering for this exam are encouraged to enroll in Math 122L (in the Fall; or Math 112L in the Spring) for the moment, as this would be the correct course choice in the event of not performing sufficiently on this exam.
