The total number of students are T = 80.
Determine the number of students who are Female od Suwanee.
[tex]10+12+8+16=46[/tex]The probability for slected person is Student or Suwanee is,
[tex]\begin{gathered} P\text{ (Female or Suwanee)=}\frac{46}{80} \\ =\frac{23\cdot2}{40\cdot2} \\ =\frac{23}{40} \end{gathered}[/tex]So answer is 23/40.
Option A is correct.
