A committee must be formed with 5 teachers and 4 students. If there are 6 teachers to choose from, and 15 students, how many dif
ZanzabumX [31]

Answer:

8190 ways

Step-by-step explanation:

Given

Teachers = 6

Students = 15

Selection

Students = 4

Teachers = 5

Required

Number of ways of selection

4 students can be selected from 15 students in:

Students= ^{15}C_4

Similarly.

5 teachers can be selected from 6 teachers in:

Teachers= ^{6}C_5

So, the required number of selection is:

Selection = ^{15}C_4 * ^6C_5

Apply combination formula:

Selection = \frac{15!}{(15-4)!4!} * \frac{6!}{(6-5)!5!}

Selection = \frac{15!}{11!4!} * \frac{6!}{1!5!}

Selection = \frac{15*14*13*12*11!}{11!*4*3*2*1} * \frac{6*5!}{1*5!}

Selection = \frac{15*14*13*12}{4*3*2*1} * \frac{6}{1}

Selection = \frac{32760}{24} * 6

Selection = 1365 * 6

Selection = 8190
