The ratio of the number of favorable outcomes to certain event and the total number of possible outcomes is called as the probability of an event.
Complementary events:
Complementary of an event represents not happening of that event. That is, if an event A is defined, then complement of event A is not occurring of event A.
Formula for finding the value of P(X≤x) is, P(X≤x)=1−P(X>X)
(a)
The probability that a respondent 18-29 years of age thinks that global warming will not pose a serious threat during his/her lifetime is obtained below:

Basic Facts [2] This is an appeal from 2009 ABQB 591 (CanLII), 473 A.R. 254. [3] Usually a judgment recites facts before law. But...
