Fill in the blank

Answer :

We need to fill the table:



i) By definition of P(A or B) under axiomatic approach we know that:


P(A B) = P(A) + P(B) – P(A B)


Using data from table, we get:


P(A B) =


ii) By definition of P(A or B) under axiomatic approach we know that:


P(A B) = P(A) + P(B) – P(A B)


P(B) = P(A B) + P(A B) – P(A)


Using data from table, we get:


P(B) = 0.6 + 0.25 – 0.35 = 0.5


iii) By definition of P(A or B) under axiomatic approach we know that:


P(A B) = P(A) + P(B) – P(A B)


P(A B) = P(B) + P(A) - P(A B)


Using data from table, we get:


P(A B) = 0.5 + 0.35 – 0.7 = 0.15


Filled table is:
