Question

guitar 11
bass 5
drums 14
keyboard 13
guitar 4
bass 8
drums 7
keyboard 8
based on these results, express the probability that a seventh grader chosen at random will play an instrument other than guitar as a decimal to the nearest hundredth.
.75
.70
.74
.73

Explanation:

Step1: Find total seventh graders

Sum all instrument counts: \(11 + 5 + 14 + 13 = 43\)

Step2: Find non - guitar count

Subtract guitar count from total: \(43 - 11 = 32\)

Step3: Calculate probability

Probability = \(\frac{32}{43}\approx0.744\), round to nearest hundredth: \(0.74\)

Answer:

.74
