Answer

Answer:

$\frac{3}{7}$

Explanation:

Step1: Identify relevant numbers

Number of adult - injured skaters wearing roller skates = 3, number of adult - injured skaters = 4 + 3=7.

Step2: Calculate probability

Probability = $\frac{\text{Number of adult - injured skaters wearing roller skates}}{\text{Number of adult - injured skaters}}=\frac{3}{7}$
