sadie attended a music stores banjo sale. she counted the types of banjos and made note of their discounts. what is the probability that a randomly selected banjo has 5 strings or 4 strings? simplify any fractions.

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

$(8 + 6)+(7 + 7)=28$

Step3: Calculate the probability

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

Answer:

$\frac{7}{8}$
