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.

In a school a fourth of a class are boys. What fraction are girls?
A fourth of the class are boys, which can be expressed as a fraction as 1/4. Since the class is made up of only boys and girls, and a fourth of the class are boys, the remaining part of the class must be girls. To find the fraction of the class that are girls, you can subtract 1/4 from 1. 1 - 1/4 = 3/4 So, 3/4 of the class are girls.
