Question

A coin is flipped 150 times. The results of the experiment are shown in the following table:


Heads Tails
63 87


Which of the following statements best describes the experimental probability of getting heads?
It is equal to the theoretical probability.
It is 8% lower than the theoretical probability.
It is 8% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.

Answer 6

A coin is flipped `150 times`.

the theoretical is \(50/50\) as the coin has got 2 sides
its either heads or tails


the experimental probability is

Heads Tails
63 87

were asked to find the probability of pulling HEADS -- thus, we can write:
\[ \frac{63}{150} \overset{/3}\Rightarrow \frac{21}{50} \]
to turn that into a percentage, we have to multiply by 2:
\[ \frac{21}{50} \times 2 \Rightarrow \frac{42}{100} \]
that means that the probability we are pulling heads is \( 42\% \)
that is indeed \(8\% \) lower than the theoretical probability. Well done!
