Question

Events A and B are such that P(A) = 3 8 , P(B) = 2 7 and P(A ∩ B) = 1 7 Work out P(A|B)

Answer 1

`(17)/(27)`

Explanation:

Given: Events A and B are such that
`P(A)=38\,,\,P(B)=27` and P(A∩B) = 17

To find:
`P(A|B)`

Solution:

Probability refers to the chances of occurrence of any event.

An event is described as an outcome of a random experiment.

A random experiment is an experiment for which outcomes cannot be predicted.

`P(A|B)=` P(A∩B) ÷ P(B) =
`(17)/(27)`
