The relative frequency of Event A in an experiment is 20%.If the experiment is performed 40 times, how many times should you expect Event A to occur?

Question

Enter your answer as a number, like this: 42

Answer 1

To find the expected number of times Event A occurs, you can use the formula:

\[ \text{Expected Occurrences} = \text{Relative Frequency} \times \text{Total Trials} \]

In this case, the relative frequency of Event A is 20%, or 0.20, and the experiment is performed 40 times.

\[ \text{Expected Occurrences} = 0.20 \times 40 = 8 \]

Therefore, you should expect Event A to occur 8 times.
