To find the probability that a seventh grader chosen at random will play the guitar, we need to calculate the number of seventh-grade students who play the guitar out of the total number of seventh-grade students.
From the data provided, we see that there are 2 seventh-grade students who play the guitar out of a total of 2 + 13 + 14 + 15 = 44 seventh-grade students.
Therefore, the probability that a seventh grader chosen at random will play the guitar is 2/44 = 0.0455.
Rounded to the nearest hundredth, the probability is approximately 0.05.
