Question

Out of 12 employees, a group of four trainees is to be sent for training of one month. (a)

In how many ways can four employees be selected? (b) What if there are two

employees who refuse to go together for training?​

Answer 1

Answer:

a= 30 ways

b = 30 ways

Step-by-step explanation:

for a

n= 12

r = 4

so number of ways  =  $\frac{12!}{4!(12-4)}$

                                 =$\frac{12 X 11 X 10 X 9 X 8}{4! X 8! }$

                                =  30 ways

for b

n = 10

r = 4

so number of ways = 30 ways

Answer 2

Step-by-step explanation:

A.Trainees should be selected on the following basis:-

• By their academic performance.
• By their spirit in doing their jobs sincerely.
• By their respect towards the company officials.
• By nature of the trainees who eager to learn something new.
• By being able to innovate something out of something else.

B. What if there are two employees who refuse to go together for training?

First of all it is compulsary of all the trainees to do the training because a training is not just of fun. People have to take it seriously as without a proper training a person will not be able to do his/her duty sincerely or dutifully.

Secondly, we have the most classic option still available that is by making them understand that they are doing a job, they are now grownups and mature and should be able understand matters of importance. They now should forget their childish behaviour and become mature.
