	Certain event	Show/Hide
	An event with probability equal to one (will definitely happen). Example: the sun will rise tomorrow
	Impossible event	Show/Hide
	An event with the probability of zero (it cannot happen) Example: Roll 13 on two 6-sided dice
	Equally likely	Show/Hide
	That have the same chance of occurring. Example: The outcomes of a fair coin toss are equally likely.
	Fair	Show/Hide
	An experiment where all of the outcomes  are equally probable. Example: If I throw one die once the probability of getting any one of the six numbers is 1/6
	Complementary events	Show/Hide
	The complement of any event A is the event [not A]. One and only one of the two events must occur.  Example: P[heads] + P[not heads] = 1	P[not A] = 1 - P[A]
	Example: If the probability that it will rain here tomorrow is 0.6, then the probability that it will not rain here tomorrow is 1− 0.6= 0.4
