1. What is the difference between theoretical probability and experimental probability?
A coin is flipped 50 times. It lands on heads 28 times and tails 22 times.
2. The experimental probability of landing on heads is .
3. The experimental probability of landing on tails is .
A spinner has 4 equal sections: Red, Blue, Green, Yellow. The spinner is spun 100 times. The results are: Red: 20, Blue: 35, Green: 25, Yellow: 20.
4. What is the experimental probability of landing on Blue?
1/4
35/100
20/100
25/100
A standard six-sided die is rolled 60 times. The number '4' appears 12 times.
5. Calculate the experimental probability of rolling a '4'. Express your answer as a simplified fraction.
6. As the number of trials in an experiment increases, the experimental probability usually gets closer to the theoretical probability.
True
False
7. A factory produces light bulbs. Out of 500 bulbs tested, 15 were found to be defective. What is the experimental probability that a randomly selected light bulb from this factory will be defective?
