They never specified there was a 100-person sample space. They said for all students across Australia. To my knowledge there are alot more than 100 students.shadiiee said:its not 0.0225
you all forgot whats going on
the answer is:
15/100 X 14/99 = 7/330
there is no replacement after one person is out theres 99 people left
therefore 9a = 7/330
