Answer
Explanation:
Step1: Find total number of students
We sum up all the values in the table. Total students = 2 + 4+ 2 + 2=10.
Step2: Find number of students who sing 0 times a week and prefer rock
From the table, the number of students who sing 0 times a week and prefer rock is 4.
Step3: Calculate probability
Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the probability = $\frac{4}{10}=\frac{2}{5}$.
Answer:
$\frac{2}{5}$
