Question

Roll a die, and you get paid what the dice shows. But if you want, you can request a second chance and roll the die again; get paid what the second roll shows instead of the first. What is the expected value?

Answer 1

1/6 is the probability mate

Answer 2

Answer:

4.25

Step-by-step explanation:

For the first dice the expected value is 3.5

if the rolled die shows 4,5,6 then stop the game, as u got more than what you expected.

if not, roll the die again.

Value from the second role=  (1/2)*3.5 = 1.75

Anwser= 4.25
