Question about a Question: Inclusion-Exclusion theorm
QUESTION:
Okey.
So, i'm curious how
P(A) = 0.5
Because
Possible numbers (sum) = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 = 11 Total
(because if two dice roll lowest number and we add them, you get two)
So why, is P(A) = 1/2?
Surely it should be = 6/11?
Thanks
