QUESTION:
Four sales representatives for a company are to be chosen at random to participate in a training program. The company has eight sales representatives, two in each of four regions. What is the probability that the four sales representatives chosen to participate in the training program will be from only two of the four regions?
ANSWER:
Step 1 of 2:
The company has to choose 4 of the 8 representatives, that is \(\left(\begin{array}{l} 8 \\ 4 \end{array}\right)\).
Then the training program will be from 2 of the 4 regions, that is \(\left(\begin{array}{l} 4 \\ 2 \end{array}\right)\)
