Measuring which physical property is most likely to produce the most precise results when trying to identify a substance? luster hardness density viscosity

I think the correct answer from the choices listed above is the third option . Measuring the density of a substance is most likely to produce the most precise results when trying to identify a substance since it can be compared to water and there are many data on it on books.

Option B) is a continuous probability distribution          

Step-by-step explanation:

Properties of a normal probability distribution:

The mean, mode and median of the data is same.It is a continuous probability distribution.The area under the curve is 1.The probability that any random variable X at a particular value is zero.

Thus, from the properties of normal distribution, the correct answer is:

Option B) is a continuous probability distribution
