There are two main methods: the empirical method and the theoretical method.
Suppose you want the probability of throwing a 6 on one roll of a die.
Empirical method: Throw the die lots and lots of times and count the total number of throws as well as the number of throws that result in a 6. The probability of throwing a six is the number of times you get a 6 divided by the total number of throws.
Theoretical method: A die is a cube with six equal faces. Assuming the die is fair, each face has an equal probability of turning up. There are no other outcomes possible (the probability of the die ending up on an edge or a vertex are assumed to be zero). So, there are six outcome, and each equally probable, so that each has a probability of 1/6.
The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
Odds against A = Probabillity against A / Probability for A Odds against A = (1 - Probabillity for A) / Probability for A 9.8 = (1 - Probabillity for A) / Probability for A 9.8 * Probability for A = 1 - Probability for A 10.8 * Probability for A = 1 Probability for A = 1 / 10.8 Probability for A = 0.0926
what is the probability of P(4or6) as a fraction, decimal and a percent
The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
To find the experimental probability of an event you carry out an experiment or trial a very large number of times. The experimental probability is the proportion of these in which the event occurs.

The answer depends on the probability of WHICH event you want to find!
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
Odds against A = Probabillity against A / Probability for A Odds against A = (1 - Probabillity for A) / Probability for A 9.8 = (1 - Probabillity for A) / Probability for A 9.8 * Probability for A = 1 - Probability for A 10.8 * Probability for A = 1 Probability for A = 1 / 10.8 Probability for A = 0.0926
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
Odds of A to B in favour of an event states that for every A times an event occurs, the event does not occur B times. So, out of (A+B) trials, A are favourable to the event. that is, the probability of A is A/(A+B).
what is the probability of P(4or6) as a fraction, decimal and a percent
The probability of an event not occurring is 1 minus the probability of it occurring.
