Answer

Explanation:

Step1: Calculate total number of banjos

$8 + 6+7 + 7+3 + 1=32$

Step2: Calculate number of 4 - string and 5 - string banjos

Number of 4 - string banjos: $8 + 6=14$ Number of 5 - string banjos: $7 + 7 = 14$ Total number of 4 - string or 5 - string banjos: $14+14 = 28$

Step3: Calculate the probability

Probability $P=\frac{28}{32}=\frac{7}{8}$

Answer:

$\frac{7}{8}$
