1. A coin is flipped 50 times. It lands on heads 28 times and tails 22 times. What is the experimental probability of landing on heads?
2. A standard six-sided die is rolled 100 times. The number '4' appears 15 times. What is the experimental probability of rolling a '4'?
3. The theoretical probability of rolling an even number on a standard six-sided die is . If you roll the die 60 times and an even number appears 27 times, the experimental probability is . In this case, the experimental probability is than the theoretical probability.
4. A spinner has 4 equal sections: Red, Blue, Green, Yellow. If the spinner is spun 80 times and lands on Red 15 times, what is the experimental probability of landing on Red?
1/4
15/80
1/5
4/15
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 quality control inspector checked 200 light bulbs and found 8 defective bulbs. Based on this data, what is the experimental probability that the next light bulb checked will be defective? If the company produces 5000 light bulbs, how many would you expect to be defective?
