You flipped a coin 20 times and got heads 12 times. What is the experimental probability of heads?
Explanation:
Hello dear student! Experimental probability is heads / total flips = 12/20. You can simplify to 3/5. Great job collecting data!
Sara rolled a die 50 times and got a 4 exactly 9 times. Experimental probability of rolling 4 is:
Explanation:
Excellent work! It's number of 4s divided by total rolls = 9/50. Keep practicing!
You tossed a coin 100 times and got tails 52 times. Experimental probability of tails is:
Explanation:
My smart friend! 52 tails out of 100 tosses = 52/100 = 13/25. You're doing beautifully!
A standard die is rolled. Theoretical probability of rolling a 3 is:
Explanation:
Excellent! 1 face with 3 out of 6 faces = 1/6. You're a probability star!
Which is the best way to find experimental probability of rolling a 2 on a die?
Explanation:
Hello my friend! We need to do the experiment many times and record results. Great question!
You want to test probability of drawing a red marble. You should:
Explanation:
My smart student! Draw many times and put back (with replacement) for fair experiment.
You spun a spinner 40 times and got blue 22 times. Experimental probability of blue:
Explanation:
Excellent calculation! 22 blue out of 40 = 11/20.
Why do we repeat probability experiments many times?
Explanation:
Excellent answer! More trials give better experimental probability.
What is replacement in marble experiments?
Explanation:
Important for fair experiments. Great understanding!
15 heads in 40 coin tosses. Experimental P(heads):
Explanation:
15/40 = 3/8. Excellent!
