A card is drawn at random from an ordinary deck of playing cards. Find the following odds.

A. Odds in favor of drawing a 5,6,7
B. Odds against drawing a king, queen, jack, or ace
D.Odds against drawing an even numbered (2,4,6,8,10)card.

Can I get some help with this question please.

• math -

there are 12 cards which are either 5,6, or 7
so Prob (a 5,6,or7) = 12/52 = 3/13

so prob (not a 5,6,or7 ) = 10/13

Odds in favour of a 5,6,or7 = (3/13)/(10/13) = 3/10
or 3 : 10 , the usual way of stating odds

Now try the others the same way, let me know what you get
