Suppose you have a random variable that is uniformly distributed between 1 and 29. what is the expected value for this random va
Kryger [21]
Assuming the distribution is continuous, you have

\mathbb E(X)=\displaystyle\int_1^{29}\frac x{29-1}\,\mathrm dx=\dfrac1{28}\int_1^{29}x\,\mathrm dx=15

If instead the distribution is discrete, the value will depend on how the interval of number between 1 and 29 are chosen - are they integers? evenly spaced rationals? etc
