# Probability Assignments/DPPs

Probability, the fascinating study of chance and uncertainty, forms an integral part of Class 11 mathematics and lays the groundwork for various applications in the Joint Entrance Examination (JEE). Understanding and applying probability concepts equips you to analyze the likelihood of events in diverse scenarios, from everyday situations to complex scientific problems.

## Overview of Probability for Class 11 and JEE

#### The Fundamental Concepts of Probability:

• Sample Space: The collection of all possible outcomes in an experiment.
• Event: A subset of the sample space representing a specific outcome or group of outcomes.
• Favorable Events: Events of interest that we are concerned with.
• Probability: A numerical measure of the likelihood of an event occurring, ranging from 0 (impossible) to 1 (certain).

#### Essential Formulas:

• Probability of an event (P(E)): Number of favorable outcomes divided by the total number of possible outcomes (P(E) = n(E) / n(S), where n(E) is the number of favorable outcomes and n(S) is the total number of outcomes in the sample space).
• Complementary events: Events that cannot occur together (P(E’) = 1 – P(E), where E’ represents the complementary event of E).
• Mutually exclusive events: Events that cannot occur simultaneously (P(A or B) = P(A) + P(B), where A and B are mutually exclusive events).
• Conditional probability: The probability of event A occurring given that event B has already happened (P(A|B) = P(A and B) / P(B), where P(A and B) is the probability of both A and B occurring simultaneously).

#### Question Types in the JEE:

The JEE tests your understanding of probability through diverse question types, including:

• Calculating probabilities: Applying formulas to determine the probability of events in various scenarios, including single events, complementary events, and combinations of events.
• Conditional probability problems: Utilizing the concept of conditional probability to solve problems involving dependent events.
• Word problems: Applying probability concepts to model and solve real-world scenarios involving games of chance, selection processes, and other situations with inherent randomness.
