Explanation / Answer

Since the sum of all the probabilities should be 0:

P(0) + P(1) + P(2) + P(3) + P(4) + P(5) = 1

0.868615786121484 + 0.124087969445926 + 0.00709074111119579 + P(3) + 0.00000289418004538603 + 0.0000000165381716879202 = 1

So,

P(3) = 1 - (0.868615786121484 + 0.124087969445926 + 0.00709074111119579 + 0.00000289418004538603 + 0.0000000165381716879202)

P(3) = 0.00020259260317701
