Answer:
![\frac{171}{1296}](https://tex.z-dn.net/?f=%5Cfrac%7B171%7D%7B1296%7D)
Step-by-step explanation:
Let’s try to go this way.
For example the number is k. It can be of course any number. So k is between 1 to 6.
The chance of rolling exactly zero ks is:
=625/1296;
The chance of rolling exactly one k is:
*
= 500/1296;
So, the chance of rolling less than two ks is: 1125 / 1296;
So, the chance of rolling at least two ks is: 171 / 1296
Answer:
120960
Step-by-step explanation:
Given that a librarian has a set of ten different books, including four different books about Abraham Lincoln.
The librarian wants to put the ten books on a shelf with the four Lincoln books next to each other, somewhere on the shelf among the other six different books.
First arrnage the 6 other books in the shelf.
This can be done in ![6! ways](https://tex.z-dn.net/?f=6%21%20ways)
Now arrange the 4 books of Lincoln
This can be done in ![4! ways](https://tex.z-dn.net/?f=4%21%20ways)
Now we have 7 places to insert Lincoln books including two corners and in between.
Thus this can be done in 7 ways
Total no of ways = ![6!(4!)(7) = 120960](https://tex.z-dn.net/?f=6%21%284%21%29%287%29%20%3D%20120960)
