Markov Bound
Given a random variable \(R\) with \(E[R] = 50\), give the smallest value \(x\) such that the Markov Bound guarantees \( \Pr[R \geq x] \leq 0.5\) under the following conditions. If the Markov bound cannot be applied, enter 6042.
-
\(R\) is non-negative
-
\(R\geq -50\)
-
\(R\geq 30\)
-
\(Pr[R \leq 50]=0.7\)
