Step-by-step explanation:
Answer: The proportion of oil tankers that had spills is
or 0.329.
Step-by-step explanation:
Since we have given that
Number of tankers is drawn = 474
Number of tankers did not have spills = 318
Number of tankers have spills = 474 - 318 = 156
Proportion of oil tankers that had spills is given by
![\dfrac{Containing\ spill}{Total}=\dfrac{156}{474}=0.329](https://tex.z-dn.net/?f=%5Cdfrac%7BContaining%5C%20spill%7D%7BTotal%7D%3D%5Cdfrac%7B156%7D%7B474%7D%3D0.329)
Hence, the proportion of oil tankers that had spills is
or 0.329.
