Quick Answer
Class 8 Mathematics Chapter 13 Probability covers the foundations of chance, sample spaces, equally likely outcomes, event probability calculations, tree diagrams, and experimental versus theoretical probability. On this page, Federal Board Grade 8 students can access complete solved textbook exercises, conceptual MCQs, short questions, and step-by-step problem solutions aligned with the 2026-2027 NBF curriculum.
Chapter Overview
Chapter 13 introduces students to probability theory and mathematical models of uncertainty. Students explore fundamental terms including random experiments, outcomes, events, and sample spaces. They learn to represent all possible outcomes systematically for single-stage experiments such as tossing a coin, rolling a standard die, or drawing a card from a deck.
The chapter progresses to theoretical probability computation using the classical ratio formula P(E) = n(E) / n(S), where the number of favorable outcomes is divided by the total number of equally likely outcomes. Students investigate the probability scale ranging from 0 (impossible events) to 1 (certain events), along with the law of complementary events where P(not E) = 1 - P(E).
In addition, the unit analyzes multi-stage compound experiments using tree diagrams and grid tables to enumerate compound sample spaces. Students examine real-life scenarios including weather predictions, quality inspection, and everyday decision-making, comparing theoretical predictions against experimental relative frequencies. All textbook review questions and probability problems are solved in detail under FBISE SLO benchmarks.
