A card is drawn at random from an ordinary deck of
playing cards. Find the following odds:
Odds against drawing a king, queen, jack, or ace
Would this not be 16/52=4/13
I would call 4/13 the probability of drawing one of those cards.
The odds against the cards being drawn is 9:4. That is the probability ratio of (not happening) to (happening).
