How many even 4 digit numbers can you form from the digits 1 2 3 and 5?
In order for the number to be even, the '2' must be the last digit. So we only need to
figure out how many ways there are to arrange the 1, 3, and 5 in the first 3 places.
The first place can be any one of 3 digits. For each of those ...
The second place can be either one of the 2 remaining digits.
And then the third place has to be the only digit that's left.
So there are (3 x 2) = 6 ways to arrange 1, 3, and 5 in the first 3 places.
That means only 6 even 4-digit numbers can be made from the digits 1, 2, 3, and 5.
And here they are:
1 3 5 2
1 5 3 2
3 1 5 2
3 5 1 2
5 1 3 2
5 3 1 2
When a coin is tossed why it appears head or tail?
Those are the names given to the two faces of a coin. From early days, coins had an image of important persons - kings, queens, emperors, on one face and that face was called heads. The reason for the other side being called "tails" is uncertain.
These are the only two outcomes of a coin being tossed. Although there is a non-zero probability of the coin falling and remaining on its edge, it is small enough to be ignored in practice.
The most important thing that the store owner should learn is that a stem and leaf plot is a huge waste of time in her circumstances. She ought to learn that using some fancy statistical technique may not always be appropriate. There are other methods that are far more useful.
A stem-and-leaf plot will tell her the range of prices of the goods that she sells, along with median and percentiles, etc. but what use is that information to a storekeeper? They may want to know what lines are selling well, which ones are not moving at all. Even more important, they may want to know how the high-profit-margin lines are doing.
Alternatively, she may wish to compare her prices with her competition, but that is useful only if she can compare prices of the same (or similar) goods. A stem-and-leaf plot does not identify the individual product lines and so she would not be able to undertake such a comparison.
All in all, I cannot see a single reason for a stem-and-leaf plot - other than to give her school-age child something to do!
