A fair 6-sided die is rolled. If I roll , n then I win n^2 dollars. What is the expected value of my win? Express your answer as a dollar value rounded to the nearest cent.
The expected value of rolling one 6-sided die is: (1+2+3+4+5+6) / 6 =3.5
Your dollar winnings should be: 3.5^2 =$12.25
Is this a brain-dead moment or your standard fare?
Solution:
Expected Value =(1/6)∗(12+22+32+42+52+62)=$15.17
