"Probability" =

the chance that an event either will or won't happen. Every event either

will or won't happen, so the sum of the two chances is ' 1 '.

"Odds" =

the ratio of the (probability that it will happen) to the (probability that it won't).

-- If (happening) and (not-happening) are equally likely, then each probability

is 0.5, and odds are 0.5/0.5 = 1 .

-- If (happening) is more likely than (not-happening) then probability of happening

is more than 0.5, and probability of not-happening is less than 0.5.

Their sum is still ' 1 ', because there is a 100% chance that the event will either happen

or not happen.

But the odds are now (more than 0.5)/(less than 0.5) = more than 1 .

Why is the probability of an event always a number between 0 and 1?

The probability of an event is defined as the ratio of favourable outcomes to total outcomes. In the case of discrete distributions these will be represented by numbers, while for continuous distribution they will be measured as areas. In either case, the first measure is non-negative and the second is positive and so the probability is greater than 0. Also, the number of favourable outcomes cannot be greater than the total so the probability must be at most 1.


Everything is possible but not everything is probable?

From a probability standpoint this is not a true statement. Probability can be equal to zero for an event, indicating that it is impossible. The difference between 'impossible' and 'improbable' from a probability standpoint is that an impossible event has a probability of 0 while an improbable event has a very, very small probability.


How does probability differ from actuality?

Probability is the chance of some outcome while actuality is the realistic chance and actual outcome of an event.


What is probability how you use or solve probability?

Probability is the chance (in percentage or decimal) of a particular event to happen. lets say that you tossed a coin. the possible events to happen are ending up with heads or tails. the probability of having a head is 50% or .5 while the probability of having a tails is 50% or .5. to solve for the probability, divide the particular event with the total number of possible events. ex. what is the probability of getting a 3 when you rolled a dice? particular event= having a 3= 1 event total number of events= having either a 1, 2, 3, 4, 5, or 6= 6 events particular event/ total number of events= 1/6 hoped i helped!


Are mutually exclusive events also complementary events?

Not necessarily. The probability of a complementary event with probability p is 1-p. Two mutually exclusive events, however, don't necessarily add up to a probability of 1. For example, the probability of drawing a King from a standard deck of cards is 1 in 13, which the complementary probability of not drawing a King is 12 in 13. The probability, however, of drawing a Heart is 1 in 4, while the probability of drawing a Club is also 1 in 4. That leaves Diamonds and Spades, which account for the remaining probability of 2 in 4.

The chance that a given event will occur usually expressed between the number 0 and 1?

The chance that a given event will occur is typically expressed as a probability, which is a number between 0 and 1. A probability of 0 means the event will not occur, while a probability of 1 means the event will definitely occur. Probabilities between 0 and 1 give us the likelihood of the event happening.

What is the difference between expecting and looking forward to?

They are practically synonyms, but expecting is knowing a certain probability of an event occurring, while looking forward to is having affect toward an event occurring.

How do you get the probability of 0?

The simplest way to get a probability of zero is to have an impossible event. For example, with a die (that's the singular of "dice") that has the numbers 1-6, getting each of these numbers has a probability of 1/6; getting the number has a probability of 0.There is another way to get a probability of zero, which occurs for certain situations that involve infinity; if you are prepared to read through some somewhat intense math, check the Wikipedia article on "Almost surely" for more details. (In this case, "almost surely" means a probability of 1; while "almost never" means a probability of 0.)


What is the difference between probability and percentage?

Probability is a measure of the likelihood of an event occurring, expressed as a fraction or decimal between 0 and 1. Percentage, on the other hand, is a way of expressing a part of a whole as a fraction of 100. Probability is used to predict the likelihood of future events, while percentage is used to compare parts of a whole.

What is the probability that a number greater that 3 appears while rolling a die?

The answer is 50 percent because if you want to roll higher than three then that is a 4, 5, or 6 or 3 out of 6 numbers.
