If you can enumerate the outcome space into equally likely events, then it is the number of outcomes that are favourable (in which the event occurs) divided by the total number of outcomes.
The formula for finding probability depends on the distribution function.
You need to know the probability of the event in question. Then the expected frequency for that event occurring is that probability times the number of times the experiment was repeated.
Expected successes= Theoretical Probability · Trials P(event) = Number of possible out comes divided by total number of possible
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
The event E must be well defined.
The formula for finding probability depends on the distribution function.
If an event occurs in n trials out of N experiments than the experimental probability of that event is n/N.
You need to know the probability of the event in question. Then the expected frequency for that event occurring is that probability times the number of times the experiment was repeated.
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.
There is no single formula of probability. The probability of a simple event in a trial is a measure of all outcomes which result in the event, expressed as a proportion of all possible outcomes.If all the outcomes have the same probability then it is the ratio of the number of "favourable" outcomes to the total outcomes. However, the definition based on numbers fails if they are not equi-probable.
Expected successes= Theoretical Probability · Trials P(event) = Number of possible out comes divided by total number of possible
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.
The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
The event E must be well defined.
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.
Probability of sure event is 1
