Probability
posted by Anna on .
A game begins with two cards being dealt from a standard deck of 2 cards. To win this game, the next card must be the same as either of these first two cards, or fall between them. If the first two cards are a 4 and a 9, what is the probability of winning the game?

you need a 4,5,6,7,8,9
There are 20 cards(above) which are in the deck to win, of a deck of 50 cards.
Pr(win)=20/50
