Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundredâ€™s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.

If you have three DIFFERENT letters, you can arrange them in 3! = 1 x 2 x 3 = 6 different ways.

3! = 1 x 2 x 3 = 6 ways.

Islands are formed in four ways. 1. Coral builds up and makes an island, 2. An underwater volcano erupts and the lava cools and slowly the build up of hardened lava forms an island, 3. The water level gets lower, exposing an island, 4. The water erodes the earth under it and deposits it in a certain area, deposited soil builds up, and slowly but surely an island forms! Islands are all different, and have many different kinds of wildlife and plant life living and growing on them. SAVE THE CORAL REEFS!!!!! :)

I'm going with 25,200 3 men out of 10 may be chosen in 10C3 ways = 10 ! / 3! 7 ! = 120 ways. 4 women may be chosen out of 10 in 10C4 = 10 ! / 4! 6! ways = 210 ways. Therefore, a committee with 3 men and 4 women can be formed in 120 x 210 = 25,200 ways.

How many different ways can we arrange 9 objects taken 3 at a time?

Any 3 out of 4 = 4. Each set can be arranged 6 ways so 24 different numbers.

There are a few different ways of writing a ratio, which are shown here:As a fraction- like 3/4, or like this 3:4 or 3 to 4

3! = 1 x 2 x 3 = 6 ways.
