In a game of checkers, there are 12 red pieces and 12 black pieces. Julio is setting up the board to begin playing.
What is the probability that the first two checkers he pulls from the box at random will be two red checkers?
Answer (3)
2 out of 24 or 2/24!
The probability of pulling out two red checkers from the box at random can be found by dividing the number of favorable outcomes by the number of possible outcomes. ;
The probability of pulling two red checkers from a box containing 12 red and 12 black checkers is 46 11 . This is calculated by finding the number of combinations of red checkers and dividing it by the total combinations of checkers. Using combinations, we calculated ( 2 12 ) = 66 for red and ( 2 24 ) = 276 for total checkers.
