The subject of Applied Maths was primarily added to the CBSE curriculum to help you align well with the social science-based applications. Probability is one such concept included in the CBSE Class 11 Applied Maths syllabus. Probability, the branch of mathematics explains how often an event is likely to occur after many repeated trials.

Now, let us understand in-depth about CBSE Class 11 Applied Maths Probability chapter. Read the complete post to know important probability formulas, topics included, and sample questions. 

What is CBSE Class 11 Applied Maths Probability?

In essence, the term “probability” refers to the possibility of the outcome of an event. Hence, as it can be understood, the branch of Probability in Applied Maths usually deals with the outcomes of an event. In most cases, the incident will be random. However, it will have a direct connection with real-life events as well.

As per the CBSE Class 11 Applied Mathematics, there are four different chapters included under the probability topic. There are two different types of Probability that are usually included in the syllabus of probability CBSE class 11 applied maths:

  • Theoretical Probability: It usually deals with the possible chances of an event that is going to happen in the near future. For example, if someone tosses a coin, then the chance of getting a tail is around 50%. It can help a student in making a stern judgment, even if he/she is not sure about the possible outcome.
  • Experimental Probability: It is yet another of the common probability topics in applied maths class 11 that focuses on possible outcomes of an incident. However, it will do the same by considering the total amount of trials. For instance, if an individual tosses a coin 10 times and gets “tails” 6 times, then its experimental probability would be 6/10.

Also, opting for the best Applied Mathematics Online Coaching would definitely help candidates to better succeed in the exam. The following are some of the important formulas of probability.

Probability Range 0 ≤ P(A) ≤ 1
Rule of Addition P(A∪B) = P(A) + P(B) – P(A∩B)
Rule of Complementary Events P(A’) + P(A) = 1
Disjoint Events P(A∩B) = 0
Independent Events P(A∩B) = P(A) ⋅ P(B)
Conditional Probability P(A | B) = P(A∩B) / P(B)
Bayes Formula P(A | B) = P(B | A) ⋅ P(A) / P(B)
