_ 1 h 2 h 3 h _ _ _ _ _ 4 hours 5 hours. _
6 hours switching between male students 6 people have 6!
space, 4 female students, who stand a 7x6x5x4x6 7x6x5x4 =
=!/10! = 1/6
.Figure b female student standing next to each other, everybody is a bundle of four female students together and counted as 1 person
so have students combine equal to 7 people = 7!
switch between female students have 4!
b = 7! x4!/10! = 1/30 1/a = b
