Answer

Answer:

$\frac{1}{4}$

Explanation:

Step1: Understand box - plot quartiles

A box - plot divides data into 4 quartiles.

Step2: Locate 30 inches on plot

30 inches is at the first - quartile (Q1) mark.

Step3: Determine the fraction

The first quartile represents 25% or $\frac{1}{4}$ of the data. So the fraction of catapults that flung a marshmallow 30 inches or less is $\frac{1}{4}$.
