Read each question carefully and answer to the best of your ability. Show all your work for short answer questions.
1. A coin is tossed 100 times. It lands on heads 58 times and tails 42 times. What is the experimental probability of landing on heads?
2. A spinner has 4 equal sections: Red, Blue, Green, Yellow. If the spinner is spun 200 times and lands on Red 45 times, what is the experimental probability of landing on Red?
1/4
45/200
4/5
1/2
3. The theoretical probability of rolling a 3 on a standard six-sided die is . If you roll the die 60 times and get a 3 twelve times, the experimental probability is .
4. A quality control inspector checks 500 light bulbs and finds 15 to be defective. What is the experimental probability that a randomly selected light bulb will be defective? Express your answer as a simplified fraction and a decimal.
5. As the number of trials in an experiment increases, the experimental probability tends to get closer to the theoretical probability.
True
False
6. A basketball player made 35 out of 50 free throws in practice. Based on this experimental probability, how many free throws would you expect him to make in his next 200 attempts?
