Error in State-action value quiz

This is in reference to the question asking us to compute the value of Q (5, left). I got an answer of 0.391 but the system is refusing to accept that as an answer stating it is the answer for Q (4, left) which it definitely is not. Can this problem be set right please?

Please post a screen capture image that shows the question you are discussing.

I have added a screenshot for your referral. Thanks for asking.

Thanks.
Can you show your steps for computing the reward value?

0 + 0 * 0.25 + 0 * 0.25^2 + 0 * 0.25^3 + 100 * 0.25^4

= 100 * 0.25^4
= 0.390625

There should only be four steps.

  • From 5 to 4 (that’s the given instruction).
  • Then follow the optimum path arrows (from 4 to 5 to 6).
