If 4 faculty members are liked from full of 8 faculty members, this can be done in 8C4 number of ways.

8C4 = 8!/(8-4)!4!

8C4 = 8!/4!4!

8C4 = 8*7*6*5*4!/4!*4*3*2

8c4 = 8*7*6*5/24

8C4 = 7*5*2

8C4 =70 ways

Similarly, 5 students space to be selected native a pool of 13 students, this deserve to be done in 13C5 variety of ways.

13C5 = 13!/(13-5)!5!

13C5 = 13!/8!5!

13C5 = 13*12*11*10*9*8!/8!*5*4*3*2

13C5 = 13*12*11*10*9/120

13C5 = 1,287 ways

The total number of ways the committee have the right to be formed is 8C4 * 13C5 = 70*1287

The total number of ways the committee have the right to be created is 90,090 ways
