1.	If `A and B` are two independent events such that `P(B) = 2/7, , P(A uu B) = 0.8` then `P(A)=`A. 0.1B. 0.2C. 0.3D. 0.4
Answer» Correct Answer - C We have, `P(A cup overline(B))=0.8 " and " P(B)=(2)/(7)` `implies P(A)+P(overline(B))-P(A cap overline(B))=0.8 " and " P(overline(B))=(5)/(7)` `implies P(A)+P(B)-P(A)P(overline(B))=0.8 " and " P(overline (B))=(5)/(7)` `implies P(A)+(5)/(7)-(5)/(7) P(A)=0.8 implies (2)/(7)P(A)=(3)/(35) implies P(A)=0.3`
