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)

How can you find a probability expressed as a percentage from a punnett square?
You can find probability form a Punnett square by turning fractions into percents
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.
What is the formula for probability fraction?
Usually, a fraction is already a probability. Like if you roll a die, the probability that you will get a 1 is 1/6. So your probability would be your fraction.
The likelihood of an event occurring?
The likelihood of an event occurring is known as the probability of occurrence. This can be calculated based on previous patterns and other factors.
Sampling error concerns natural variation between samples is always present and can be described using probability Is this true?
No, it is not true. Probability can be used to describe some properties of the variation but not all.
