Summary of Probability for Kerala Board Class 10 Mathematics. Key concepts, important points, and chapter overview.
Overview
Probability is a branch of mathematics that deals with the likelihood or chance of occurrence of events. In our daily life, we often use words like 'probably', 'likely', 'possibly' to express uncertainty about future events. This chapter introduces us to the concept of quantifying these chances usin
Key Concepts
Probability calculated based on actual experiments
Probability calculated based on actual experiments or observations. Formula: P(E) = Number of times event occurred / Total number of trials. Example:
Probability calculated using mathematical reasoning without
Probability calculated using mathematical reasoning without conducting experiments. Formula: P(E) = Number of favorable outcomes / Total number of pos
Sample space is the set
Sample space is the set of all possible outcomes of an experiment. An event is a subset of the sample space. For example, when rolling a dice, sample
Outcomes that have equal chances
Outcomes that have equal chances of occurring. Essential assumption for classical probability. Examples include fair coin tosses, unbiased dice throws
Two events are complementary if one
Two events are complementary if one is 'not' the other, and together they cover all possible outcomes. For any event E, P(E) + P(E') = 1, where E' rep
