If A, B, C are three events of a sample space such that P(B) =\(\frac{3}{2}\) P(A) and P(C) = \(\frac{1}{2}\)P(B) then which of the following is correct
1
P(A ∪ C) = \(\frac{7}{13}\) when A, B, C are exhaustive and mutually exclusive events
2
\(\frac{10}{13}\) ≤ P(B ∪ C) = ≤ 1 when A, B, C are exhaustive events
3
P(C) = \(\frac{7}{13}\) when A, B, C are exhaustive events
4
P(A ∪ B ∪ C) = P(A) P(B) P(C)
