PROBABILITY & PREDICTIONS #2

Directions: You can use probability & proportions to make predictions about the future. First, figure out the probability of a single event. Then set up and solve a proportion to calculate how many times that event is likely to happen in a certain number of trials. Use the spinner below, along with you knowledge of coins and regular number cubes (dice), to predict the events listed below.

EVENT PROPORTION PREDICTION

1) If you flip the coin 200 times, how many tails? 100 tails

2) If you spin the spinner 40 times, how many 4’s? __________________

3) If you roll the cube 60 times, how many 6’s? __________________

4) If you flip the coin 96 times, how many heads? __________________

5) If you spin the spinner 50 times, how many even numbers? __________________

6) If you roll the cube 60 times, how many numbers less than 3? __________________

7) If you flip the coin 74 times, how many tails? __________________

8) If you spin the spinner 75 times, multiples of 2? __________________

9) If you roll the cube 120 times, how factors of 6? __________________

10) If you spin 90 times, how many numbers greater than 3? __________________
