One card is selected from a deck of playing cards. Determine the probability of selecting a card greater than nine or a black card. Show your work
------
I'm assuming 10,Jack,Queen,King are the only cards greater than 9.
----
P(> 9 OR black) = P(>9) + P(black) - P(>9 AND black)
------
= [4*4/52] + [26/52] - [2*4/52]
----
= [16+26-8]/52
---
= 34/52
----
= 17/26
