Introduction to expected value of x tutoring:

In this topic we will discuss about expected value of x tutoring for discrete random variable and some exam questions. Expected value is the fundamental thought in probability, in a sense more general than probability itself. The expected value of a real-valued possibility variable offers a compute of the center of the distribution of the variable. Tutoring is defined as a process of a personality working in the education of others, either individually or in group.

Formula for expected value of x tutoring:

The following formula for expected value of x tutoring which is used to compute expected value for discrete random variable shows given below.

Expected value E(x) = sum (xi. P (xi))

x = discrete random variable

P(x) = probability distribution

Example problems for expected value of x tutoring:

Expected value of x tutoring - Example 1:

1) Evaluate the expected value for the discrete chance variable (1/16). Where x is begin from 0 to 4.

Solution:

Expected value is recognized for the discrete possibility variable by utilize the formula,

E(x) = sum xi P (xi)

E(x) = 0 (1/16) + 1 (1/16) + 2 (1/16) + 3(1/16) + 4(1/16)

E(x) = 0 + 0.0625 + 0.125 + 0.1875 + 0.25

E(x) = 0.625

The Expected value is: 0.625

Expected value of x tutoring - Example 2:

2) Evaluate the expected value for the discrete possibility variable. (1/15). Where x value starting from 1 to 6.

Solution:

Expected value is recognized for the discrete...
