Arrangements of 10 different things taken 4 at a time
To find the number of arrangements of 10 different things taken 4 at a time in which one particular thing always occurs, we can follow the steps below:
Step 1: Select the fixed item
- Since one particular thing always occurs, we first select that particular item.
- There is only 1 way to choose this fixed item.
Step 2: Select the remaining 3 items from the remaining 9
- After selecting the fixed item, we need to select 3 more items from the remaining 9.
- This can be done in ^9C3 ways, which is equal to 84.
Step 3: Arrange the 4 selected items
- Once we have selected the 4 items, we need to arrange them.
- This can be done in 4! ways, which is equal to 24.
Step 4: Calculate the total number of arrangements
- To find the total number of arrangements, we multiply the number of ways in each step.
- Therefore, the total number of arrangements = 1 (fixed item) * ^9C3 (selecting 3 items) * 4! (arranging 4 items)
- Total arrangements = 1 * 84 * 24 = 2016.
Therefore, the number of arrangements of 10 different things taken 4 at a time in which one particular thing always occurs is 2016.
