Question

Robotics manufacturers can design mobility features in one of several ways. Robots can have legs, wheels, both legs and wheels, or no legs or wheels. Using a random sample of 106 robots, researchers found that 63 had legs only, 20 had wheels only, 8 had both legs and wheels, and 15 had no legs or wheels. What's the relative frequency of robots with both legs and wheels?

Answer 1

`\text{\huge{\red{\underline{SOLUTION}}}}`


`\textbf{\red{Total robots = 106}}`


`\textbf{\red{Number of robots with both legs}}\\ \textbf{\red{and wheels = 8}}`


`\textbf{ \red{Relative frequency} }= \red {(8)/(106) * 100 = 7.55 }`


`\textbf{ \red{Relative frequency is 7.55 percent}}`
