Answer:
0.0313
Step-by-step explanation:
Given that in the shipment of 71 vials, only 13 do not have hairline cracks
Probability of not having a hairline cracks = 
If you randomly select 2 vials from the shipment
(Probability of not having a hairline cracks)' =
= 
what is the probability that none of the 2 vials have hairline cracks.
i.e 
= 0.183 × 0.171
= 0.0313
Hence, the probability that none of the 2 vials have hairline cracks = 0.0313
25 to the 2 or 25^2
Explanation:
There are 2 25’s 25x25, so the amount of exponents is the same as the number of repeated numbers
Let the fraction be 5/5
remaining= 50%*5/5-1/5= 2.5/5-1/5=1.5/5
percentage =1.5/5*100=30%
Whole numbers are numbers without decimal points greater than 0.
The set of whole numbers is:

In the introductory part of this solution, I stated that:
- Whole numbers do not have decimal point
- The smallest whole number is 0
This means that the following numbers are whole numbers:
1, 9, 10, 67
While the following numbers are not:
-1, 9.0, 1.0, -67
Let W be the set of whole numbers; the set is:

The dots after 4 means the set still continues
