Question

If you want to talk about the sample space of everyone who passed MAT 150, then you can write: S = {x | } An is a subset of a sample space. We usually write this with an A, B, C, etc, instead of S. Given the sample space S = {t | t > 0}, where t is the number of years a Gallaudet student attends college before graduating, then how can we write the event A that a student graduates before his/her fifth year? A = {t | }Sometimes, an even is empty, which means it's impossible for it to happen. We call this the set, and we write it with phi . For these notes, I will sometimes write that as null instead of the symbol. Let A be the event that a roll of the die returns a number that is both even and less than 2. How can you write A? A = The of an event A with respect to S is the subset of all elements of S that are not in A. We write the complement of A by the symbol A'. I think it's easier to think of the complement of A as being "not A."

Explanation / Answer

S={x|x0}

event

A={t|0t5}

null

A=null

complement
