Question

Camille attended a music store's banjo sale. She counted the types of banjos and made note of their discounts. 4 strings 5 strings 6 strings 25% off 4 4 8 50% off 6 8 3 What is the probability that a randomly selected banjo has 6 strings or 5 strings? Simplify any fractions.

Answer 1

`\text{probability = }\frac{\text{ number of favorable outcomes}}{\text{ total number of outcomes}}`

number of banjos with 6 or 5 strings: 4 + 8 + 8 + 3 = 23

total number of banjos: 4 + 6 + 4 + 8 + 8 + 3 = 33

The probability that a randomly selected banjo has 6 strings or 5 strings is:

`p=(23)/(33)`
