Question

If X is continuous random variable then expected value is given by *
2 points
No value such as expected value
P(X)
∫X P(X)
∑X P(X)​

Answer 1

Answer:

The expected value of random variable X is often written as E(X) or µ or µX. The expected value is the 'long-run mean' in the sense that, if as more and more values of the random variable were collected (by sampling or by repeated trials of a probability activity), the sample mean becomes closer to the expected value.

Answer 2

Given:

X is a continuous random variable

To find:

To find the expected value.

Explanation:

• The expected value of "X" can be represented as $E(X)$.
• The continuous random variable's expected value can be represented as the continuously expected catalog.

Solution:

X is a continuous variable

The expected value of the continuous variable is the summation of all the values.

Hence, the expected value will be ∑X P(X)​
