Best Answer

Expressing a probability in terms of a fraction rather than a decimal can give the reader a clearer idea of the chances of an outcome out of all the possible outcomes.

Some examples:

Chance of a coin landing on heads: 1/2 (1 head on a 2-sided coin)

Chance of a dice landing on 4: 1/6 (1 '4' on a 6-sided dice)

Chance of getting an ace in a pack of cards: 4/52 (4 aces in a 52-pack of cards)

Does probability have to do with fractions?

Yes. Probability can be expressed i n fractio ns.


Are fractions and probability the same?

NO, but that is a great question since probability is often expressed as a fraction. Here is the difference. If P(x) is the probability that even x happens, this value must be between 0 and 1. So fractions such as 1/2 or 2/1112 are all fine. Many fractions, such as 4/3 cannot be a probability since they are greater than one. Similarly, -1/2 cannot be a probability value since it is less than 0/

What is the probability that you will get a fraction greater the 316 over 17?

The answer depends on what population of fractions you have in mind. If considering all fractions, the answer is 1.


What is the difference between a probability and a fraction?

The probability is always a fraction except when it is 0 or 1. If a probability = 1 then it will definitely happen. If the probability is 0 then it will not happen. If you toss a fair coin the probability of heads is 1/2, and the probability of tails is 1/2. These fractions are representations of the probabilities. Not all fractions are representative of probabilities. Fractions can be used to represent a portion of a whole. Like what portion of a class is boys, and what portion is girls: If there are 8 boys and 7 girls, then the 8/15 of the class is boys, and 7/15 of the class is girls.
