For those seeking additional help, probability Class 11 solutions and notes can provide a deeper understanding of each topic. These notes break down complex problems and theories into understandable parts, making it easier for students to grasp the subject matter. All these resources are designed to prepare students for both their Class 11 exams and for future opportunities in fields that require a strong understanding of probability and statistics.

So, in conclusion, mastering the concept of probability in Class 11 is crucial for a strong foundation in maths and for future success in competitive exams. Using a combination of worksheets, MCQs, Class 11 notes, and NCERT solutions can significantly improve your understanding of this vital topic.

probability definition

Probability is a measure of the likelihood of a specific event happening among all possible outcomes. It is a mathematical way to express how certain we are that a particular event will occur. The value of probability ranges from 0 to 1, where 0 means the event will not happen, and 1 means the event is certain to happen. A probability of 0.5, for instance, indicates that there is an equal chance of the event occurring or not occurring.

probability formula

In Class 11, students are introduced to the basics of probability. The core probability formula that is usually taught at this level is the "Classical Probability" formula, which is expressed as:

()=Number of favorable outcomesTotal number of possible outcomes

Here, () is the probability of event happening.


If you toss a fair coin, there are two possible outcomes: Heads (H) or Tails (T). If you're interested in the probability of getting a Head, the formula would be:


Conditional Probability:

Another important concept in Class 11 is "Conditional Probability", given by the formula:


Here, () is the probability of occurring given that has already occurred.

Binomial Probability:

Although it's usually covered in more advanced classes, some curricula introduce the "Binomial Probability" formula in Class 11:


Here, is the number of successes, is the number of trials, is the number of successful outcomes, and is the probability of success in a single trial. (,) is the binomial coefficient, often read as "n choose k."

probability sampling and non probability sampling

Probability Sampling:

In probability sampling, every individual in the population has a known, non-zero chance of being selected. This method is often used when the research aims for a high level of accuracy and generalizability. Common types of probability sampling include:

  1. Simple Random Sampling: Every individual has an equal chance of being selected. This is similar to drawing names from a hat.

  2. Systematic Sampling: Researchers select samples based on a fixed interval. For example, they might choose every 10th name on a list.

  3. Stratified Sampling: The population is divided into subgroups (or "strata") based on a specific characteristic like age, and then samples are randomly selected from each subgroup.

  4. Cluster Sampling: The population is divided into clusters, usually geographically, and then a few clusters are randomly selected for study.

Non-Probability Sampling:

In non-probability sampling, not all individuals have a known or equal chance of being selected. This method is often quicker and easier but less reliable for generalizing results. Types of non-probability sampling include:

  1. Convenience Sampling: Researchers choose individuals who are easiest to reach or most convenient to study.

  2. Judgmental or Purposive Sampling: The researcher selects specific individuals because they possess traits important to the study.

  3. Snowball Sampling: This is often used for hard-to-reach or hidden populations. One participant refers the researcher to another potential participant.

  4. Quota Sampling: Researchers select a specific number of individuals based on certain traits, but without ensuring that everyone has an equal chance of being chosen.

    Importance of Understanding Probability in Class 11

    Understanding probability in Class 11 is crucial for grasping more advanced concepts in statistics, mathematics, and other sciences.
