Chapter 7: Probability
Figure 7-9:
Elements in
A
B
or (
A
or
B
)
Note:
In the union of events, elements common to different events are not
replicated.
Example 7-13
:
Given the probability that
only
event
A
will occur is 0.4,
the probability of
only
event
B
will occur is 0.2, and the probability that
both
events
A
and
B
will occur is 0.3. Depict this information on a Venn
diagram.
Solution:
The information is displayed in
Figure 7-10
. Note that the sum
of the probabilities in the Venn diagram equals 1.
