Making Predictions

1. 1. Martin flips a coin. What is the probability that the coin will land on heads?

2. 2. Use the theoretical probability from number 1 to answer the following question:
   Martin flips the coin 64 times. How many times can Martin expect the coin to land on heads?

3. 3. A spinner is divided into five equal sections labeled 1 to 5. What is the probability that the spinner will land on 3?

4. 4. Use the theoretical probability from number 3 to answer the following question:
   If the spinner is spun 60 times, how many times can you expect the spinner to land on 3?

5. Harriet rolls a number cube. What is the probability that the number cube will land on 3 or 4?

6. 6. Use the theoretical probability from number 5 to answer the following question:
   If Harriet rolls the number cube 39 times, how many times can she expect to roll a 3 or 4?

7. A bag contains 6 red and 10 black marbles. If you pick a marble from the bag, what is the probability that the marble will be black?

8. 8. Use the theoretical probability from number 7 to answer the following question:
   If you pick a marble, record its color, and return it to the bag 200 times, how many times can you expect to pick a black marble?

9. Gill rolls a number cube 78 times. How many times can he expect to roll an odd number greater than 1?

10. Jenna flips two pennies 105 times. About how many times can she expect both coins to come up heads?
