Eg - if I have a fair die and I want to roll it 20 time and get the total number of times that it landed on which side, [4, 1, 7, 5, 2, 1]
Web1 You say you know the probability of each side of the die and there are about 20 sides. Let's denote the sides i for i = 1, 2,..., 20. So your answer is exactly the definition-- p -value ( i 0) = ∑ { i: p ( i) ≤ p ( i 0) } p ( i). Note that I disagree slightly with your definition. I think the < in your sum should be ≤. Share Cite
