1) you choose 3, possible ways: choose 3 women, 1 solution, choose 3 men; 3 solution, choose 2w 1m: \(\displaystyle{3}\cdot{4}={12}\), choose 2m 1w: \(\displaystyle{6}\cdot{3}={18}\). Total \(1+4+12+18=35\)
2) from 3 women you choose 2, that is 3 ways, and from 4 men you choose 1, that is four, multiplying \(3 \cdot 4=12\) ways.
3) there is 12 ways from 35, that means probability is \(\displaystyle\frac{{12}}{{35}}\).

In how many ways can 8 people be seated in a row if a.) there are no restrictions on the seating arrangement(answer is \(\displaystyle{8}!={40},{320}\)) , b.) persons A and B must sit next to each other? (Answer: 10,080) , c.) there are 4 men and 4 women and no 2 men or 2 women can sit next to each other? (Answer: 1,152) , d.) there are 5 men and they must sit next to one another? (Answer: 2,880) , e.) there are 4 married couples and each couple must sit together? (Answer: 384). I need to see the steps to solve questions 10b to 10e. I quickly looked through the corresponding chapter on combinatorial analysis and I went over topics such as the multinomial theorem, the basic principle of counting, the binomial theorem, and representing the number of possible combinations of n objects taken r at a time as "n choose r" .
