Probability is
A
always expressed as a ratio
B
a 50% chance that an event will occur
C
the mathematical chance that an event will occur
D
a 3:1 chance that an event will occur
Explanation: 

Detailed explanation-1: -The probability of an event occurring is intuitively understood to be the likelihood or chance of it occurring. In the very simplest cases, the probability of a particular event A occurring from an experiment is obtained from the number of ways that A can occur divided by the total number of possible outcomes.

Detailed explanation-2: -Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Detailed explanation-3: -When the chance is defined in Mathematics, it is called probability. Probability is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

Detailed explanation-4: -The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Detailed explanation-5: -It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
