In a game of checkers there are 12 red pieces and 12 black game pieces.Julio is setting up the board to begin playing. what is t
he probability that the first two checkers he pulls from the box at random will be two red checkers . Can you please show me how to work this out ?
1 answer:
Since there are equal numbers of pieces, the chances of Julio getting a red on the first pull is 12/24 or 1/2 (reduced)
However on the second pull there are only 11 reds (Julio pulled one out) out of 23 remaining pieces so the chances of pulling the second red are 11/23
Now multiply those possibilities:
1/2 x 11/23 and you will get 11/46 which is the probability of pulling two reds in a row. 11/46 is the answer.
