WeBWorKassignment8isdueon03/17/2012at12:01am.This assignment contains questions on discrete and continu-ous random variables. You will calculate probabilities of certainevents for given random variables, find probability density func-tions and cumulative distribution functions, and calculate expec-tations, variances and standard deviations for the given randomvariables.Notes For HW8- none so far.WebWork notation forsinˆ{-1}(x)is arcsin(x) or asin(x).Fortanˆ{-1}(x)it is arctan(x) or atan(x).The primary purpose of WeBWorK is to let you know if youare getting the right answer or to alert you if you get the wronganswer. Note that you have a limited number of attempts avail-able to answer a question, in order to discourage “guessing”.If you are having trouble figuring out your error, you shouldconsult the book, ask a fellow student, visit the Math LearningCentre, or ask your professor for help. Don’t spend a lot of timeguessing – it’s not efficient or effective.You can use the Feedback button on each problem page tosend e-mail to the TAs and professors. Make sure that your e-mail address is set correctly under ”Change Email” in order toreceive a response.Give 4 or 5 significant digits for (floating point) numericalanswers.For most problems when entering numerical answers, youcan if you wish enter elementary expressions such as2ˆ3in-stead of8,sin(3*pi/2)instead of-1,eˆ(ln(2))instead of2,(2+tan(3))*(4-sin(5))ˆ6-7/8instead of27620.3413, etc.A list of functions which WeBWorK understands can befound at.
