Which of the following best represents the probrability that the selected college student will be a male student or a gradruate student?

Answer 1

Graduated : 480 among which 240 are (F and graduated) and 240 are (Male and graduated)
40% of 2020 are Male : 808 ==> (Male and non graduated) : 808 - 240 = 568
therefore :
Male or Graduated = (Male and non graduated) + Graduated (M or F)
= 568 + 480
= 1048
and therefore :
1048/2020 = 51.88%
