HELPING EMILY SOLVE PROBLEMS (CONTINUED) 3. Emily did an experiment with a bag that contained 25 marbles. One of the marbles was black, five were white, four were red, and the rest were green. She drew the marbles from the bag one at a time. The marble drawn was not placed back in the bag. Emily made a chart so that after each draw she would know the probability of drawing a certain color next. The following is the order of the first ten marbles drawn: green, green, green, white, red, green, white, white, red, green Fill in Emily's chart. Probability of Drawing Color Color drawn 1. green 2. green 3. green 4. white 5. red 6. green 7. white 8. white 9. red 10. green 4. Emily was working on probability that involved two events. She knew that to find the probability that a 1 or 4 would appear when a die was tossed, she must add the probability of the two events. Each probability is :, so Emily added : + : = 1, or ;, or 33%. She also knew that to find the probability of a head and tail appearing when a coin was tossed, she must multiply the probabilities of each event. Each probability is ? so Emily multiplied 2 x 2 =1, or 25%. Emily wanted to make a probability experiment using the die and coin. She was going to toss a die and then toss the coin. Emily wanted to know the probability of a 1 on the die or a head on the coin. She knew that the "or" in the problem was a signal that she must add. Show Emily how to find the probability that a 1 on the die or a head on the coin will appear
