Practice Questions
You flip a fair 2 sided coin 10 times. You get 6 heads and 4 tails.
You decide to flip the coin 1 more time.
\(\textbf{1)}\) \( \text{What is the theoretical probability of getting a heads?} \)
\( \frac{1}{2}=50\%\)
\(\textbf{2)}\) \( \text{What is the experimental probability of getting a heads?} \)
\( \frac{6}{10}=\frac{3}{5}=60\%\)
\(\textbf{3)}\) \( \text{What is the theoretical probability of getting a tails?} \)
\( \frac{1}{2}=50\%\)
\(\textbf{4)}\) \( \text{What is the experimental probability of getting a tails?} \)
\( \frac{4}{10}=\frac{2}{5}=40\%\)
You roll a fair 6 sided dice 50 times.
You record the data in the following table.
| \(\underline{\text{Roll Value}}\) |
\(\underline{\text{Frequency}}\) |
| \(1\) |
\(8\) |
| \(2\) |
\(10\) |
| \(3\) |
\(5\) |
| \(4\) |
\(7\) |
| \(5\) |
\(9\) |
| \(6\) |
\(11\) |
\(\textbf{5)}\) \( \text{What is the theoretical probability of rolling a 5?} \)
\( \frac{1}{6}\approx 16.7\%\)
\(\textbf{6)}\) \( \text{What is the experimental probability of rolling a 5?} \)
\( \frac{9}{50}=18\%\)
\(\textbf{7)}\) \( \text{What is the theoretical probability of rolling an even number?} \)
\( \frac{3}{6}=50\%\)
\(\textbf{8)}\) \( \text{What is the experimental probability of rolling an even number?} \)
\( \frac{28}{50}=56\%\)
