Correct answer: (B) P(Y≥u)≤P(X≥u) for every u≥0.; (D) E X>E Y.
Explanation
Since Y≤X,{Y≥u}⊂{X≥u},proving B. The CDF inequality goes in the reverse direction from A. Continuity makes P(X integer)=0,so X−Y>0 almost surely and it is bounded by 1. Its expectation is strictly positive,hence E X>E Y. **B,D**.
