Answer:
[tex]R=\dfrac{8}{13}[/tex]
Step-by-step explanation:
Inbounds in the volleyball match = 8
Out of bounds in the volleyball match = 5
Total serves = inbounds + out of bounds
= 8+5
= 13
The ratio of services that were inbounds to total serves is given by :
[tex]R=\dfrac{8}{13}[/tex]
Hence, this is the required solution.
