9 3/10- 1 7/10 is 7.6 or 7 3/5
Answer: The first and second options are random samples.
First, assign numbers and drawing the number from a bowl would be a great way to get a random sample. Everyone has the same chance of being selected.

3/5 is the greatest because when you change 3/5 to percantage, it will be 60%.
<span>2 liters" only shows one significant figure. This "2 liters" can be anything from 1.9 liters to 2.1 liters. Actually, to be more strictly correct, the 2 liters can be between 1.5 liters and 2.4 liters. Either of these bounds would be 2 to the nearest ONE's place.
The biggest percent error would be between 2 and 1.5, which is a volume error of 0.5 liters.
Thus: (0.5/2)*100=25% C: is your Answer</span>
