Define conditional probability.

1.	Define conditional probability.
Answer» The probability of occurrence of one event under the condition that another event has already occurred is known as conditional probability. The probability that B will occur under the condition that Alias already occurred is denoted by P(B/A). P(B/A) = Total number of favourable cases of B/Total number of favourable cases of A) Similarly, The probability that A will occur under the condition that B has already occurred is denoted by P(A/B).

Answer»

The probability of occurrence of one event under the condition that another event has already occurred is known as conditional probability.

The probability that B will occur under the condition that Alias already occurred is denoted by P(B/A).

P(B/A) = Total number of favourable cases of B/Total number of favourable cases of A)

Similarly, The probability that A will occur under the condition that B has already occurred is denoted by P(A/B).
