A school director must randomly select 6 teachers to part in a training session. There are 34 teachers at school. In how many different ways can these teachers be selected, if the order of selection does not matter.

Respuesta :

Answer:

Total possible ways to select 6 teachers from 34 teacher are [tex]^{34}C_6=1344904[/tex].

Step-by-step explanation:

It is given that total number of teachers at a school is 34.

The school director must randomly select 6 teachers to part in a training session.

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

Where, n is total possible outcomes and r is number of selected outcomes.

Total teachers = 34

Selected teachers =6

Total number of possible ways to select 6 teachers from 34 teacher is

[tex]^{34}C_6=\frac{34!}{6!(34-6)!}[/tex]

[tex]^{34}C_6=\frac{34\times 33\times 32\times 31\times 29\times 28!}{6!(28)!}[/tex]

[tex]^{34}C_6=1344904[/tex]

Therefore total possible ways to select 6 teachers from 34 teacher are [tex]^{34}C_6=1344904[/tex].
