Theoretical probability

सैद्धांतिक प्रायिकता

In this Class 9 Mathematics topic from Introduction to Probability, students learn how to predict the likelihood of events using a theoretical approach. They explore sample spaces, outcomes, events, and equally likely results, then apply the formula: probability = number of favourable outcomes ÷ total number of possible outcomes. Through simple examples involving coins, dice, cards, and everyday situations, students practise identifying outcomes, calculating probabilities, and expressing results as fractions, decimals, or percentages. The topic also builds a clear understanding of why probability lies between 0 and 1.
