Question:
Find the probability of neither a 5 or spade from a deck of cards
Solution:
A standard deck of cards has 52 cards.
We will first find the number of cards that are either a 5 or a spade:
There are 4 5's (one for each suit) and 13 spades.
However, the 5 of spades has been counted two times, so the number of cards that are either 5 or a spade equals 4+13-1=16.
There are then 52-16=36 cards that are neither 5 nor spades.
The probability of drawing neither a 5 nor a spade from a standard deck is therefore
P(~5∧~spade)=36/52=9/13
