How to find Expectation of a Random Variable √X in probability

How to calculate Expected Value of Random Variable √X

In case of Discrete Random Variable:

• E[x]= Σ (x) * P(x)
• E[√X]= Σ (√x) * P(x)

In case of Continuous Random Variable:

• E[x]= ∫ (x) * f(x) dx
• E[√X]= ∫ (√x) * f(x) dx

Integrate on all values of X
