# CBSE Class 10 Maths Chapter 15 – Probability Class 10 Notes

## Probability Class 10 CBSE Revision Notes

Probability Class 10 Notes deals with the fifteenth chapter of CBSE Class 10 Maths. First of all, students in class 9 have already studied the experimental probabilities of events whose basis is upon the results of actual experiments. Furthermore, consider an experiment of tossing a coin 1000 times and the frequencies of the outcomes were that head was 455 times and the tail was 545 times. Consequently, the empirical probability of the head comes out to be 455/1000, which is 0.455 and that of obtaining a tail is 0.545.

Furthermore, students must note that the basis of these probabilities is the results of an actual experiment of tossing a coin 1000 times. Therefore, experts call them as experimental or empirical probabilities. Most noteworthy, the basis of experimental probabilities happens to be the results of actual experiments and sufficient recordings of the happening of events. Also, students must understand that these probabilities are only â€˜estimatesâ€™. If another similar experiment takes place for another 1000 times, then one may get different data providing different probabilities estimates. Thus,Â probability class 10 notes will help explain this in detail.
