Answer:

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)=(1)/(13){*}(1)/(12){*}(1)/(11)

P(JQK)=(1)/(1716)

P(KQJ)=(1)/(13){*}(1)/(12){*}(1)/(11)

P(KQJ)=(1)/(1716)

P(JQK or KQJ)=(1)/(1716)+(1)/(1716)

P(JQK or KQJ)=(1)/(858)≈0.0012
Answer 2
Answer: that would be 1/858 for jack, queen, or king of those 13 cards.
