a bag contains a number of colored gum balls: 2 green, 10 orange, 5 blue, 3 yellow. your friend candy randomly picks a gum ball, then you do the same. what is the probability that candy selects a yellow gun ball and you select an orange gun ball?
add up the number of balls to get 20. The chance of getting orange is 1/2 or .5, and the chance of getting yellow is 3/20, or .15. Then multiply the two fractions.
