Acellus Find the expected value of a random variable x having the following probability distribution. 0 1 2 3 4 5 Probability 1/8 1/4 3/16 1/4 1/16 1/8 ​

"2.25" is the right answer.

Step-by-step explanation:

According to the question,

The expected value will be:

=

=

=

=

=

=

=

Thus the above is the right approach.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
