Conceptually, probability may be defined as ______.

A) the total number of possible outcomes divided by the total number of events
B) the total number of possible outcomes
C) the likelihood of the occurrence of a particular outcome of an event given all possible outcomes
D) the number of ways an outcome can occur plus the number of ways an outcome cannot occur

Probability is the likelihood of a particular outcome occurring out of all possible outcomes for an event. It is a measure of uncertainty or randomness in an event. Option A is incorrect as it only gives the ratio of possible outcomes to events without any consideration of the likelihood of each outcome. Option B is incorrect as it only considers the number of possible outcomes without any consideration of the likelihood of each outcome. Option D is incorrect as it doesn't give a correct definition of probability.
