Explanation / Answer

8) P(all students fom 2nd section) = (11/17)*(10/16)*(9/15)*(8/14)*(7/13) = 0.0747

9) P(1 student from 1st section) = (6C1)*(11C4)/(17C5) = 0.3200

10) P(at most 2 students from 2nd section) = [(11C0)(6C5) + (11C1)(6C4) + (11C2)(6C3)]/(17C5) = 0.2054

Formula used: Number of ways for combination divided by total number of ways of selection
