Question

According to the general equation for conditional probability if P(A B)=2/9 and P(B)=1/3, what is P(A B)

Answer 1

• P(A | B) = 2/3

----------------------

The general equation for conditional probability is:

• P(A | B) = P(A B) / P(B)

Using this equation and the given values, we can calculate P(A | B) as follows:

• P(A B) = 2/9 and P(B) = 1/3

• P(A | B) = P(A B) / P(B)
• P(A | B) = (2/9) / (1/3) = (2/9) * (3/1) = 6/9 = 2/3

Therefore, P(A | B) = 2/3.
