What type of probability uses a knowledge of sample spaces as opposed to observations to determine the numerical probability of an event?

Classical probability

Step-by-step explanation:

Classical property is that type of probability or statistical concept that deals with the  measurement of the odds or likelihood of some event.It is that form of probability that is simplest in approach and includes the equal likelihood of happening or occurrence of an event.In order to determine the numerical probability of an event, it makes use of the knowledge of sample spaces in contrast with the observations.It takes a proper note of an event in order to calculate its probability and also it deals with the likelihood of a certain event rather than making observations.
