Explanation:

Step1: Calculate total 8th graders

Add all 8th grade student counts:
$10 + 7 + 10 + 2 = 29$

Step2: Identify bass-playing 8th graders

Number of 8th graders on bass: $7$

Step3: Compute probability as decimal

Divide bass count by total 8th graders:
$\frac{7}{29} \approx 0.24$

Answer:

0.24
