A survey was taken of 49 people to see if they watch basketball and/or soccer games on television. The results are shown in the

emmasim [6.3K]

Answer:

$\begin{array}{cccc}&\text{Watch basketball}&\text{Don't watch basketball}&\text{Total}\\\text{Watch soccer}&7&12&19\\\text{Don't watch soccer}&17&13&30\\\text{Total}&24&25&49\end{array}$

Step-by-step explanation:

From the diagram you can see that

17 people watch only basketball;
7 people watch both basketball and soccer;
12 people watch only soccer;
in total, 17+7+12=36 people watch some sports;
so, 49-36=13 people do not watch sports.

So, you can fill the table in following way

$\begin{array}{cccc}&\text{Watch basketball}&\text{Don't watch basketball}&\text{Total}\\\text{Watch soccer}&7&12&19\\\text{Don't watch soccer}&17&13&30\\\text{Total}&24&25&49\end{array}$
