It is given that


P(A)=(1)/(3)


P(B)=(2)/(5)


P(A\cap B)=(3)/(5)

According to the union formula:


P(A\cup B)=P(A)+P(B)-P(A\cap B)


P(A\cup B)=(1)/(3)+(2)/(5) -(3)/(5)


P(A\cup B)=(1)/(3)+(2-3)/(5)


P(A\cup B)=(1)/(3)-(1)/(5)


P(A\cup B)=(5-3)/(15)


P(A\cup B)=(2)/(15)

Therefore the value of P = (A ∩ B) is
\bold{(2)/(15)}.
