428 students were surveyed about their preferences of sports. 146 students like football, 144 students like baseball, and 45 stu
ella [17]

This is what we already know:


\left[\begin{array}{cccc} &YB&NB&total\\YF&45&[unknown]&146\\NF&[unknown]&[unknown]&[unknown]\\total&144&[unknown]&428\end{array}\right]


And using this information, we can fill the table out. Remember that everything must add up to the total in the column and row. The complete table looks like this:


\left[\begin{array}{cccc} &YB&NB&total\\YF&45&101&146\\NF&99&183&282\\total&144&284&428\end{array}\right]


Using the complete table, we see the fraction for students that only like baseball is \frac{99}{428} and students who only like football is \frac{101}{428} . All you need to do is add these fractions together to get your answer.


\frac{99}{428} +\frac{101}{428} =\frac{200}{428}


In short, 200 students only like one of the two sports.
