p=0.8765
Step-by-step explanation:
Let the following variables be represented as below:
Total Set,t=17
Def,d=3
Not Def,n=14
Purchases,p=8
The number of ways the hotel can receive at least one defective set in a purchase of 8 sets is calculated using the combination:-

The total number of possible combinations to make a three digit number is 60
<u>Explanation:</u>
Given:
Five numbers are there = 1, 2, 3, 4, 5
We have to form three digit number
The number should not be repeated
Consider 3 dashes for 3 digits : ___ ___ ___
The first dash can be occupied by any 5 digits.
The second dash can be occupied by 4 digits
The third dash can be occupied by 3 digits
Thus, number of possible combinations to make a three digit number is
= 5 X 4 X 3
= 60
Therefore, total number of possible combinations to make a three digit number is 60
