which is the joint relative frequency for the people who can only see the sunset?\n$\frac{5}{38}$\n$\frac{7}{38}$\n$\frac{12}{38}$\n$\frac{14}{38}$
Answer
Explanation:
Step1: Recall joint - relative frequency formula
Joint relative frequency = $\frac{\text{Frequency of the cell}}{\text{Total frequency}}$
Step2: Identify the frequency of the cell and total frequency
The people who can only see the sunset means the cell where there is sunset and no sunrise, which has a frequency of 12. The total frequency is 38.
Step3: Calculate the joint - relative frequency
The joint relative frequency = $\frac{12}{38}$
Answer:
$\frac{12}{38}$
