Islands can be formed through volcanic activity, where underwater eruptions create land as lava cools and solidifies. They can also emerge from the accumulation of sand and sediment, often seen in river deltas or coastal areas. Additionally, tectonic activity can uplift land, creating islands as a result of earthquakes or plate movements.
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 hundred’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.
Three items can be arranged in (3!) (3 factorial) ways, which is calculated as (3 \times 2 \times 1 = 6). Therefore, there are 6 different ways to arrange 3 items. These arrangements can be represented as permutations of the items.

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.

3 different ways
Mother 3 is set on a different island at a different time.
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.
