## Important Topics for NCERT Maths Exemplar Solutions Class 11 Chapter 16 – Probability

Probability

Probability is the count of the uncertainty of different phenomena, numerically. It can consist of any positive value from 0 to 1. The words ‘doubt’, ‘probably’, ‘most probably’, ‘chances’, etc., used in the declarations above include an element of uncertainty.

Random Experiment

An experiment is considered to be a random experiment if there are more than one possible outcomes and it’s impossible to calculate the outcome in advance.

Outcome

All possible results of an experiment are known as its outcome.

Kay Facts of Probability

• An experiment of rolling a die. All possible outcomes are 1, 2, 3, 4, 5, or 6. The set of all these outcomes is represented as {6, 5, 4, 3, 2, 1} and is called the sample space.
• An experiment of tossing two coins. Since either coin can turn up Heads or Tails, so, all the possible outcomes are both Head (HH), both Tail (TT), Head and Tail (HT), Tail and Head (TH). Therefore, the sample space (S) can be denoted as {HT, TT, TH, HH,}.
• Let consider a random experiment, Let ‘S’ be the sample space. The ‘P’ is a real-valued function whose range is the power set of S and [0, 1] is the range interval.
• For any event X, P(X) ≥ 0
• P(S) = 1
• If X and Y are mutually exclusive events, then P(X Y = P(X) + P(Y)

Events in Probability

An event is a subset of S. An empty set is also considered as an impossible event. The set A′ is called the Complementary event.
