Hi Kangkan/ Subhayu/anyone pls help me with the doubts I have. Thanks.

Q 1:The avg speed is 5 m/s. If she must have reached  5 m/s she must have run at 4 m/s at some point isn't it. Shouldn't the answer be a?

Q 38: Isn't all the locations between [0.2,0.7] pareto optimal? In this interval its not possible to make one person better off by making the other person worse off. As the distance increases for any one person, if the nuclear plant if moved in either direction .

Q 41: Are we implying that if exactly one has a positive probability, the other has 0 probability abd hence P(A).P(B)=0=P(AnB) ??

Q 50: Just one doubt here.The probability that X = b is not defined for a continious probability function right? Is it right to say it has positive probability.
