Answer

Explanation:

Step1: Calculate total number of students

$5 + 6+8 + 9+10 + 8+10 + 4=60$

Step2: Calculate number of bass - playing students

$6 + 8 = 14$

Step3: Calculate the probability

The probability $P$ that a randomly - chosen student plays the bass is $P=\frac{14}{60}$.

Step4: Convert to percentage

$P=\frac{14}{60}\times100%=\frac{1400}{60}% \approx 23%$

Answer:

$23%$
