This
delightful 8-page self-contained Microworld represents one of the earliest
works in the Mathwright Library. Written in 1993 at a WorkShop at Morehouse
College, it remains one of the nicest
introductions to the ideas and methodology of probability at the Library.
You may find it as: Bernoulli Trials.
The
WorkBook gives the opportunity to experiment with Bernoulli Trials. The term
"Bernoulli Trials" refers to a sequence of trials, each of which has two possible
outcomes, generically called success and failure. The trials are independent
and the probability of success is the same for each trial. This probability
is denoted p and is called the parameter of the process. The probability of
failure on each trial is 1 - p, which is sometimes denoted q. It uses Access
Data Bases, together with bar charts to show the outcome of simulated trials.
This
Microworld makes use of a Database as Active Data Object. This means that
you do not have to have a database program to use these data bases, but you
should have the MS Access Database or the MS Access 97 Database
installed as a Data Source Name. So be sure that your setup is ready
to use them.
In
Windows 95/98/ME, just go to the Control Panel, and under ODBC Data Sources,
select the User DSN tab. If MS Access Database or MS Access
97 Database is already installed, you are all set! Otherwise, press the
Add... button, and double-click on the Microsoft Access Driver (*.mdb)
entry. Then, in the Data Source Name, type MS Access Database.
