The table shows the results of spinning a four-colored spinner 50 times. Find the experimental probability and express it as a decimal.
A. 0.1
B. 0.4
C. 0.8
D. 0.2
3) THe table below shows the results from flipping two coins. How does the experimental probability of getting HH compare to the theoretical probability of getting HH?
outcome: HH HT TH TT
Number of times tossed: 28 22 34 16
PLease explain this, but don't give the answer yet
Experimental probability is based on actual results obtained from an experiment, while theoretical probability is based on the number of possible outcomes. In this case, the theoretical probability of getting HH is 1 out of 4 possible outcomes, or 1/4. To compare this to the experimental probability of getting HH, we need to calculate the number of times HH occurred out of the total number of coin tosses (28 + 22 + 34 + 16 = 100).
oops forgot the answer choices:
THe experimental probability is 3% greater than the theoretical probability
The theoretical probability is 3% greater than the experimental probability
THe experimental probability is equal to the theoretical probability
The experimental probability is 7% greater than the theoretical probability
To find the experimental probability of getting HH, you need to add up the number of times it occurred (28) and divide by the total number of coin tosses (100). This gives an experimental probability of 28/100 or 0.28.
The theoretical probability was calculated to be 1/4 or 0.25.
Comparing the two probabilities, we see that the experimental probability is greater than the theoretical probability by 0.03 or 3%. Therefore, the answer is:
The experimental probability is 3% greater than the theoretical probability.
Thanks, taht was actually the answer I chose so I am glad it was right
You're welcome! I'm glad to hear that my explanation was helpful. Don't hesitate to ask if you have any more questions!
baseball player gets on base 7 times and strikes out 5 during a tournament. What is the experimental probability of the player getting on base?
5/7
7/12
5/12
7/10
The experimental probability of the player getting on base is the number of times they get on base divided by the total number of attempts. In this case, the player gets on base 7 times and strikes out 5, so the total number of attempts is 7 + 5 = 12.
Therefore, the experimental probability of the player getting on base is:
7/12
So, the answer is:
B. 7/12
You flip a coin 20 times and get tails 15 times, you flip the coin 80 more times what do you expect to happen to the experimental probability of getting tails as you increase the number of trials?
will get closer to 50%
will remain at 75%
will always be greater than theoretical
will get closer to 100%
The experimental probability of getting tails is the number of times tails occurred divided by the total number of coin flips. In this case, you got tails 15 times out of 20 flips, which is an experimental probability of 15/20 or 0.75.
As you increase the number of trials (by flipping the coin 80 more times in this case), the experimental probability of getting tails is likely to move closer to the theoretical probability of getting tails. The theoretical probability of getting tails on a fair coin is 0.5.
So, the expected outcome is:
The experimental probability of getting tails will get closer to 50%.
