Probability

# How do you find the experimental probability that a particular result will occur?

###### Wiki User

You carry out the experiment a large number of times. Count the number of times it was carried out (n). Count the number of times in which the particular outcome occurred (x). Then, the experimental probability for that even is x/n.

You carry out the experiment repeatedly. If the selected result is observed s times out of n repeats, then the probability is s/n.

### What is experimental probability vs theoretical probability?

Theoretical probability is what should occur (what you think is going to occur) and experimental probability is what really occurs when you conduct an experiment.

### What is meant by the term probability?

Probability means - The likelihood that a particular event will occur.

### What is the difference between mathematical probability and experimental probability?

Mathematical probability is how many times something is projected to occur, where as experimental probability is how many times it actually occurred. For example, when discussing the probability of a coin landing heads side up... Mathematical probability is 1:2. However, if you actually carryout an experiment flipping the coin 5 times the Experimental probability may be 2:5

### What is the different between theoretical and experimental probability?

experimental probability involves conducting numerous amounts of trials of an experiment and theoretical is determining that a certain outcome will occur through reasoning and calulation.

### What is the probability of an event occurring to the probability that it will not occur?

The probability that an event will occur plus the probability that it will not occur equals 1.

### What is the likelihood that a particular event will occur?

The likelihood of an occurrence is called its probability.Other terms associated with probability are chance, risk, and possibility.

### The likelihood that a particular trait will occur in offspring?

probability the likelihood that a particular event will occur codominance a condition in which neither of two alleles for a trait is dominant nor recessive

### How would one intreprete a p value of 0.000?

Probability = 0 can be interpreted as an outcome that can not occur after infinite independent trials. A relative frequency (also termed an empirical or experimental probability) of zero, even after a large number of trials, can not have the same interpretation. If, after say a million trials, a particular outcome has not occurred, the correct interpretation based solely on the data, is that the outcome is highly unlikely to occur, but not impossible. The conclusion of "impossible to occur" and "highly unlikely to occur" are mutually exclusive conclusions. If an event is highly unlikely to occur, then there exists a probability &gt; 0 of occurring, and after infinite trials, this event must occur.

### Probability of an event occurring to the probability that it won't occur?

These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).

### Does Probability predict what will definitely occur?

The laws of probability predict what is likely to occur, not necessarily what will occur.

### What is the definition of probability in math?

Probability is the likelihood that some particular event will occur. It is expressed as a number between 0 and 1, where 0 means the event will not occur, and 1 means the event will occur. Values in between 0 and 1 indicate the relative likelihood, i.e. "probability", that the event will occur. For instance, the probability of tossing heads on a fair coin toss is 0.5, the probability of rolling a 3 on a standard die is 1 in 6, or about 0.1667, and the probability of drawing an ace of spades from a standard deck of 52 cards is 1 in 52 or about 0.01923.

### What does probability of an event mean?

Probability is the likelihood, expressed in numerical or ratiometric terms, that an event will occur. A probability of 1 means that the event will occur. A probability of 0 means that the event will not occur. A probability of 0.5 means that the likelihood of the event occurring is equal to the likelihood of it not occurring. For instance, a fair coin has a 0.5 probability of being heads, and a 0.5 probability of being tails. Defined formally, probability is the number of permutations of the desired outcome divided by the number of permutations of all possible outcomes. Take a standard six-sided die, for instance. There are six permutations. One of them is a 1, so the probability of rolling a 1 is 1 in 6, or about 0.1667. Probability is not assured. If you roll a die 600 times, you will not necessarily get 100 1's. Over the long run, you will approach that outcome, but each trial will have different results. This is the difference between theoretical probability and experimental probability - theoretical being the mathematical estimate - experimental being the observed results.

### Probability of an impossible event is?

an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur

### What is theoretical probability?

the probability a certain event will occur :-)

### What do you mean by probability?

Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.

### What part of speech is probability?

The word probability is a noun. Probability is an event that is likely to occur.

### Why probability is equal to one?

One is the probability, or certain to occur.

### What is the definition of probability?

The likelihood that a particular event will occur is called probabilityThe ratio of the wanted outcomes divided by the possible outcomes gives a fraction or ratio usually expressed as a percentage.The likelihood of an event occuring.

### Probability is the what that something will or will not occur?

Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.

### If the probability that an event will occur is 1 then the event is certain to occur?

Yes, the probabilty scale is from one to zero so is the probability is 0 it will definitely not occur
