Probability is the chance or likelihood of a thing to happen. It is the extent to which an event is likely to occur. It is seen that how many times a thing occur out of the total one.
In this example, there are 5 vowels in MATHEMATICAL, these are, A, E A, I, A.
There are total 12 letters in this word. So the probability is 5/12. So there is 5/12 chances of vowels to occur whenever a piece of paper is taken out of the bag.
