They can be arranged 5! or 120 ways.

There are two ways to look at this problem; gender or person. Gender (M=Male, F=Female); There is only one way and that is MFMFMFMFM. By person, you have 9 places to fill. The first is 5 males could be placed there, the next 4 females could be placed there, the next 4 males can be placed there, the next 3 females can be placed there and so forth. So in this instance there are 5*4*4*3*3*2*2*1*1 = 2880 arrangements. Another way is just 5!*4!=2880. Here 5! is for men and 4! for women. ie. Men can be arranged in 5 ways and women can be arranged in 4 ways.

Any way you like!

If this is for homework, I would state your reasoning for excluding (or including) that set. Count all the options up, and you have 8 different ways you can arrange the rows with the exclusion.

The number of different ways that 8 computer operators can be seated in a row is the same as the number of permutations of 8 things taken 8 at a time. That is 8 factorial, which is 40,320. Think of it this way... You have 8 choices for the first seat, 7 choices for the second seat, 6 choices for the third seat, and so on to 1 choice for the last seat. That is 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1, otherwise known as 8 factorial.
