b. P(2;4)
c. P(6;3)
d. P(10;7)
e. P(9;8)

Part 2
A copy machine randomly puts out 10 blank sheets per 500 copies processed. Find the probability that in a run of 300 copies, 5 sheets of paper will be blank.
Part 3
A recent study of robberies for a certain geographic region showed an average of 1 robbery per 20,000 people. In a city of 80,000 people, find the probability of the following:
a. 0 robberies
b. 1 robbery
c. 2 robberies
d. 3 or more robberies

part 4.
In a 400 page manuscript, there are 200 randomly distributed misprints. If a page is selected, find the probability that it has 1 misprint.

1.
Probability of event that occurs:

Probability of event that does not occur:
(') =
(') =
(')=

2.
A copy machine randomly puts out 10 blank sheets per 500 copies processed.

the probability that in a run of copies, sheets of paper will be blank is
≈
3.

The Binomial distribution has the probability
function
=,,,.....,
where
For people, we expect robberies.
a)

use the source to compute

Using Poisson with

Using Poisson with lambda=4

d)
p( highlight(x >=3))= p( 3 through 20000)

This uses normal approximation instead of Binomial because is too large and is too small.
4.
Presuming there are of total pages with misprints, there is a % probability of discovering one on any given page.
which is %
