A card is picked from a standard deck of 52 cards. Determine the odds against and the odds in favor of selecting a jack

Question

odds of selecting a jack from a deck of CARDS

 

Answer 1

In a standard deck of 52 cards, there four jacks (one in each suite).  That means 4 Jacks and 48 other cards.

 

If it is equally likely that any one of the 52 cards may be drawn, the:

  odds against drawing a Jack are    48:4

  odds in favor of drawing a Jack are:          4:48

 

[Note: "odds" are not the same as "probability."]

Answer 2

For = 4/52 = 1/13

 

Against = 12/13
