A ratio is a comparison of the relative size of two different things. Probability is the change that something will (or will not) occur. Probability can be expressed as a ratio of Yes to No (or, "will occur" to "won't occur"). That is, Probability is the relative size of Yes to No. So, if something is said to have a 60% Probability of occurring, what that is indicating is that, out of 100 tries, 60 will be the outcome indicated. While probability is usually expressed as a percentage, it is entirely possible to express it as a ratio. In the aforementioned example, a 60% Probability of occurrence could also be said to be a 60:40 (or, reduced, 3:2) ratio in favor of happening.
probably means that something or which is not sure . LIKE :- I PROBABLY GET THIS ANSWER RIGHT.
A probability of one means that the outcome will definitely occur.Not asked, but answered for completeness sake - a probability of zero means that the outcome will definitely not occur. Probability always lies between zero and one, inclusive.
If an event has a probability of occurring p, then the probability of it not occurring is 1 - p. This is because the probability of something happening is always 1, i.e. p + (1 - p) = 1.
probability
an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur
probability
Zero.
probability is the chance or likely hood that something will 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.
probability
Probability is the likelihood of something happening. It is the extent to which something is likely or unlikely to occur.
Probability is a numeric expression of the "odds" that something will happen.
The probability that an event will occur plus the probability that it will not occur equals 1.
The probability that something will happen is the number of times that that something can occur divided by the number of times that anything can occur. An example would be to consider a standard deck of 52 cards. There are 4 sevens in the deck, so the probability of drawing a seven is 4 in 52, or 1 in 13, or about 0.0769.
These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
