Standard deviation is calculated by the square root of the variance. Now, how do we solve the variance? The variance is the <span>average of the </span>squared differences from the Mean. Calculating the variance, we can obtain a standard deviation of <span>3.74. Therefore, the correct answer is option A.</span>
Answer:
The volume in liters is 2.041165665 liter.
Step-by-step explanation:
Given : Clare wants to mail a package that weighs 
pounds.
To find : What could be its volume in liters ?
Solution :
We know that,
Pound (lb) is a unit of Weight used in Standard system.
Liter (l) is a unit of Volume used in Metric system.
To convert 1 pound into liter is
1 pound (lb) = 0.45359237 liter (l)
pounds in simpler fraction is 
Converting into liter,
pound (lb)=
liter (l)
pound (lb) = 2.041165665 liter (l).
Therefore, the volume in liters is 2.041165665 liter.

The events are independent. By definition, it means that knowledge about one event does not help you predict the second, and this is the case: even if you knew that you rolled an even number on the first cube, would you be more or less confident about rolling a six on the second? No.
An example in which two events about rolling cubes are dependent could be something like:
Event A: You roll the first cube
Event B: The second cube returns a higher number than the first one.
In this case, knowledge on event A does change you view on event B (and vice versa): if you know that you rolled a 6 on the first cube you don't want to bet on event B, while if you know that you rolled a 1 on the first cube, you're certain that event B will happen.
Conversely, if you know that event B has happened, you are more likely to think that the first cube rolled a small number, and vice versa.
