Answer: 4/30 or 0.13
Step-by-step explanation:
Among the seventh graders, 12 students play guitar, 9 students play bass, 4 students play drums, and 5 students play keyboard.
12+9+4+5=30
There are a total of 30 seventh graders. 4 of them play drums.
Probability that a seventh grader chosen at random will play the drums:
4/30=1.3333333....
Round to the nearest hundreth
The probability as a decimal to the nearest hundredth is 0.130.13.
