I copied this question from youtube on same lecture but I am not sure either what is the answer for this question:
The sum of a discrete probability distribution should always be 1, correct? For the distribution shown at 6:00, sum_x Q(x) = 1+epsilon which doesn't equal 1.

Somebody please answer if we are missing something?

@Sonam Singh : You can think of it as P(x) = {0.33,0.33,0.33,\epsilon}
