Question

Please help me
The teacher of a seventh-grade class flipped a coin 100 times. The students recorded the results in the table shown below:

Side of Coin Landed On Heads Tails
Number of Flips 54 46
Which of the following best describes the experimental probability of getting heads? (1 point)

a
The experimental probability is the same as the theoretical probability.

b
The experimental probability is 4% lower than the theoretical probability.

c
The experimental probability is 4% higher than the theoretical probability.

d
The experimental probability cannot be concluded from the data in the table.

Answer 1

Thoughts?

Recall that the theoretical probability is what happens *on average* based on the total number of favorable outcomes vs total outcomes. For flipping a coin, there are two sides and only one is heads, so the probability of getting heads is 1/2 or 50%.

Now, the *experimental* probability is the probability of getting heads based on the actual data. Divide (number of heads)/(total # of coin flips) from the data in the table, then multiply by 100% to convert to a percentage.

Finally, compare the theoretical vs actual probabilities.
