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
Answer:
16.7 (rounded)
Step-by-step explanation:
Divde 200 by 12 and that should give you your answer if I'm wrong I'm so sorry!
The answer is x=150 degrees.
You fist multiply the area by two. Then you divide that by the height.
