Answer» <P>Step-by-step EXPLANATION: This is the given question is of LAW OF TOTAL PROBABILITY. Formula for LAW OF TOTAL PROBABILITY :-) \begin{gathered}P(A) = P(E_1).P( A | E_1)+ \\ P(E_2).P( A |E_2) + P(E_3).P( A| E_3) + ... .\end{gathered} P(A)=P(E 1
).P(A∣E 1
)+ P(E 2
).P(A∣E 2
)+P(E 3
).P(A∣E 3
)+....
