Probability

What is probability?

Probability measures the likelihood of an event occurring, ranging from 0 to 1.

What is a sample space?

The sample space is the set of all possible outcomes of an experiment.

How do you calculate the probability of an event?

P(E) = Number of favorable outcomes / Total number of outcomes.

What is the addition rule in probability?

For any events A and B, P(A ⋃ B) = P(A) + P(B) – P(A ⋂ B).

What is conditional probability?

Conditional probability is the probability of event B occurring given that event A has occurred, P(B | A) = P(A ⋂ B) / P(A).

Probability is an important chapter for the students of Class 9, 10, 11, and 12.
