## anonymous one year ago A coin was flipped 150 times. The results of the experiment are shown in the following table: Heads Tails 90 60 Which of the following best describes the experimental probability of getting heads? It is 10% higher than the theoretical probability. It is 10% lower than the theoretical probability. It is equal to the theoretical probability for this data. The experimental probability cannot be concluded from the data in the table.

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

The experimental probability of heads is 90/150 = 0.6 If the coin was fair, the theoretical probability of heads is 0.5 Therefore the experimental probability of heads is $\large \frac{0.6-0.5}{0.5}\times\frac{100}{1}=20\ percent$ higher than the theoretical probability of heads. So none of the answer choices is correct.
