If P(A)=0.4, P(A∪B)=0.7, then the probability of B will be maximum when A and B are:
Correct Answer: Option B
Explanation:
P(A∪B)=P(A)+P(B)-P(A∩B). To maximize P(B) given P(A∪B)=0.7 and P(A)=0.4, set P(A∩B)=P(A)=0.4 (i.e., A⊂B). Then 0.7=0.4+P(B)-0.4 => P(B)=0.7 max.

Chain base index numbers are particularly useful for analyzing:
Correct Answer: Option C
Explanation:
