rt2007 what is sample space ? can anyone explain ?
bdoggprod They are defining the sample space as all of the possible outcomes for the experiment.
TammTamm Thanks AN for explaining stats the way it's taught in undergrad. It makes it easier to understand than the readings.
Kennyk11 It should be noted that C is wrong because you can only pick one color and one side of the coin, since they are mutually exclusive (two events that cannot occur at the same time).

I was very pleased with your notes and question bank. I especially like the mock exams because it helped to pull everything together.
