This document provides a comprehensive overview of probability and linear equations in mathematics. It covers various concepts such as calculating probabilities of events, understanding uncertainty, and representing situations using linear equations in two variables. The exercises and unsolved problems presented aim to enhance the reader's understanding of these mathematical topics. From determining probabilities of outcomes in coin toss experiments to solving linear equations based on real-life scenarios like income levels and family sizes, this document serves as a valuable resource for students and individuals looking to strengthen their mathematical skills.
Here are some sample questions
Question 1:
In a bag containing 4 red and 8 blue marbles, what is the probability of drawing a red marble?
Question 2:
If a coin is tossed 400 times and the outcomes are 280 heads and 120 tails, what is the probability of getting a head and the probability of getting a tail?
Question 3:
In a class of 50 students where 35 students passed and 15 failed, what is the probability that a student chosen at random passed the examination?
