Answer:
Step-by-step explanation:
Given: separate all the clubs from a deck of cards and pick 3 of those 13 cards.
To find: probability that the cards are jack, queen, and king in ascending or descending order
Solution: Ascending and descending are mutually exclusive , thus
P(JQK)=[tex]\frac{1}{13}{\times}\frac{1}{12}{\times}\frac{1}{11}[/tex]
P(JQK)=[tex]\frac{1}{1716}[/tex]
P(KQJ)=[tex]\frac{1}{13}{\times}\frac{1}{12}{\times}\frac{1}{11}[/tex]
P(KQJ)=[tex]\frac{1}{1716}[/tex]
P(JQK or KQJ)=[tex]\frac{1}{1716}+\frac{1}{1716}[/tex]
P(JQK or KQJ)=[tex]\frac{1}{858}[/tex]≈0.0012
