Question

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 56 44


Which of the following best describes the experimental probability of getting heads?
The experimental probability is same as the theoretical probability.
The experimental probability is 6% lower than the theoretical probability.
The experimental probability is 6% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.

Answer 1

Answer: Third option is correct.

Explanation:

Since we have given that

Number of heads = 56

Number of tails = 44

Total number of flips = 100

So, Probability of getting head is given by

`(56)/(100)=0.56`

Theoretical probability of getting head is given by

`(50)/(100)=0.50`

There is a difference of

0.56-0.50=0.06 = 6%

Hence, the experimental probability is 6% higher than the theoretical probability.

Therefore, Third option is correct.
