Ede4ka [16]

Solution:

we are given that

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.

\\  {30}_C_6=\frac{25*26*27*28*29*30}{1*2*3*4*5*6}\\
\\  {30}_C_6=593775

Hence the required number of ways is 593775.
