The probability you're asked to find is
where
is the event that either event occurs (A, B, or both), and
is the event that both events occur.
Recall that
which means
You're told that
,
, and (if I'm reading the diagram correctly)
.
So,
Another way of seeing this is that the event A consists of the regions "A not B" and "A and B". So the probability that "A not B" occurs is
Similarly, B consists of "B not A" and "A and B", so you have
So the probability that A or B, but not both, occur is
To get the percent error you take the offset and divide the total by it, so it would be 10/125
Answer:
Volume measures capacity. For example, the volume of a bowl is the amount of space inside the bowl or how much water, for example it would take to fill the bowl. In the metric system of measurement, the most common units of volume are milliliters and liters.
The answer as a decimal is -42.6
