Solve each problem. Scheduling Tiffany has the prerequisites for six different computer science courses. In how many ways can she select two for her schedule next semester?

So there are eight employees we're working at attain for fee in Chicago. So Manager wants to choose do employees, although it four show e and show being, if one is selected for a and then from there, meaning it will be a step critical official. So there are how many possible combinations eight into seven. For them hands, it is basics.

So this question we're being told that it has three different channels. Channels. We'd have been channel that ST of incomes. So temps, up from 7 to 8. The truth. 10 9 to 10. And what of China knows for each time? So we have three choices. Tresses. So, uh, the total number of ways to arrange all these is just three times the country he posted 27. Where is a watching?

In this problem of basics of contemporary, we have to use any matter described in this section to solve each problem. And we have given problem If to light has eight courses to choose. Strong, how many ways can he arrange? He said you if he must be four of them. We are talking about cellular and in serial order matters. There are other matters. We take arrangement his permutation. So they use permutation to take. And said. All the court says from the eight courses We have to pay four out of eight courses. So it will be a permutation for using the formula for permutation. NPR equal to N. Factorial upon. In minus r. Factorial comparing this quick two expressions we have in equal to eight and are equal to four. Putting the value in the formula. We held a pictorial upon 8 -4. Victoria expanding this eight factorial we have eight multiplied by seven, multiplied by six, multiplied by five. Multiplied by four victoria. And in the terminator we help for victoria. Now we can divide this four factorial by this four factorial. So the hell! After simplifying this explosion, eight multiplied by six. Multiplied seven, multiplied by six, multiplied by five, Multiplying this four days. Eat. We have 1680. So There will be 1680. said you'll this will be a final answer.

So the person kind of running schedule in uh or ways If he picks four out of the eight courses, so uh so then we can put that into the equation oh because eight eight minus, or it's like that, so it's going To end up being eight oh yeah, which is equal to eight Just equal to one 1680.
