Example 8-13:
Ten items are selected at random from a production line.
What is the probability of selecting
more than
8 defectives if it is known that
the probability of a defective item from this production system is 0.05?
Solution:
Let the number of defectives be represented by
X
. Then
X
will
be a binomial random variable with
= 10,
= 0.05 and varying
values.
The probability of selecting more than 8 defectives is equivalent to finding
P
(
X
> 8). This situation is displayed in
Figure 8-14.
