1 PROBABILITY UNLIKELY – LESS ½ LIKELY – MORE ½ CERTAIN - ALL IMPOSSIBLE- CAN’T HAPPEN, 0 EQUAL CHANCE- SAME NUMBER

2 The marbles pictured below are gray, white and black. They are placed in a bag and one is drawn at random.

3 Which color marble is least likely to be drawn from the bag?

4 What is the probability of drawing the black marble from the bag?

5 What is the probability of drawing a marble that is not white?

6 Would you be more likely to draw a marble that is not black or a marble that is not gray? Explain your answer.

7 If three more black marbles were added to the bag, what would be the probability of drawing a black marble?
