Conditional Probability Examples

Conditional Probability Examples:

The codicillary anticipation of an accident B will be the anticipation that the accident will action accustomed the ability that an accident A has already occurred. This anticipation is accounting P(B|A), characters for the anticipation of B accustomed A. In the case area contest A and B are absolute to the codicillary anticipation of accident B accustomed accident A is artlessly the anticipation of accident B, that is P(B)..

Let us accede the contest A and B are not independent, again the anticipation of the circle of A and B (the anticipation that both contest occur) is authentic by

P(A and B) = P(A)P(B|A).

From this definition, the codicillary anticipation P(B|A) is calmly acquired by adding by P(A):

P(B|A)= P(A and B)/ P(A)

This announcement is alone accurate if P(A) is greater than 0.
