Introduction for expected value of sample information tutor:
Expected value is the main thought in probability, in an intellect more general than probability itself. The expected value of a real-valued selection variable offers a compute of the center of the distribution of the variable. More considerably, by taking the expected value of various functions of a common random variable, we can calculate a lot of interesting features of its distribution, including spread and correlation. Tutor is a personality working in the education of others, either separately or in group.
Formula for expected value of sample information tutor:

The following formula for expected value of sample information tutor which is used to compute expected …show more content…

Solution: Expected value is recognized for the discrete possibility variable by utilize the formula, E(x) = sum xi P (xi) E(x) = 0 (1/13) + 1 (1/13) + 2 (1/13) + 3(1/13) + 4(1/13) E(x) = 0 + 0.0769 + 0.1538 + 0.2307 + 0.3076 E(x) = 0.769 The Expected value is: 0.769
Expected value of sample information tutor - Example 2:
2) Evaluate the expected value to the discrete chance variable 1/6 from 2 to 7.
Solution:
The formula for finding the expected value for a discrete chance variable is E(x) = sum xi P (xi) Here, i = 2 to 7 E(x) = 2 (1/6) + 3 (1/6) + 4(1/6) + 5(1/6) + 6(1/6) + 7(1/6) = 0.3333 + 0.5 + 0.6666 + 0.8333 + 1 + 1.1666 = 4.4998 Answer value is: 4.4998
Additional problems for expected value of sample information tutor:
Expected value of sample information tutor - Example 3:
3) Evaluate the expected value for the discrete possibility variable. (1/18). Where x value begins from 1 to 6.
Solution:
Expected value formula for discrete random variables: E(x) = sum xi P(xi) E(x) = 1 (1/18) + 2 (1/18) + 3 (1/18) + 4(1/18) + 5 (1/18) + 6 (1/18) E(x) = 0.0555 + 0.1111 + 0.1666 + 0.2222 + 0.2777 + 0.3333 E(x) = 1.1664 The Expected value is: 1.1664
