Unit eight probability lesson for experimental probability answers
1. What is the difference between experimental probability and theoretical probability?
Experimental probability is based on actual observations and measurements, while theoretical probability is based on mathematical calculations and assumptions.
2. How is experimental probability calculated?
Experimental probability is calculated by finding the ratio of the number of desired outcomes to the total number of outcomes observed in an experiment.
3. A student rolls a six-sided die 50 times and gets a 3 on 10 of the rolls. What is the experimental probability of rolling a 3?
Experimental probability of rolling a 3 = Number of times a 3 was rolled / Total number of rolls
Experimental probability = 10 / 50 = 0.2 or 20%
4. A basketball player makes 25 out of 50 free throw shots in a game. What is the experimental probability of the player making a free throw shot?
Experimental probability of making a free throw shot = Number of successful shots / Total number of shots
Experimental probability = 25 / 50 = 0.5 or 50%
5. A spinner has 4 equal sections labeled A, B, C, and D. If the spinner is spun 50 times and lands on section C 15 times, what is the experimental probability of landing on section C?
Experimental probability of landing on section C = Number of times section C was landed on / Total number of spins
Experimental probability = 15 / 50 = 0.3 or 30%
