With a deck containing 52 cards what's the probabilty of choosing at random a black card or not a face card?
--------------------
# of black cards = 26
---
# of face cards = 3*4 = 12
----
# of face cards that are black cards = 6
===============
P(black or not face) = P(black) + P(not face) - P(black and not face)
= 26/52 + 40/52 - 20/52
---
= 46/52
---
= 23/26
