It depends. Normally, there are about 50 students if it is in a public school. But it may go down to a better size of 40, even 30 in some private schools.
3 students can be chosen from a class of 30 in (30 x 29 x 28) = 24,360 ways.But each group of the same 3 students will be chosen in six different ways.The number of different groups of 3 is 24,360/6 = 4,060 .
it would be 3/10 of the class.
