Why is probability so important to learn? When will we use it in the
real world?

Dear Brianna,

It's one way to think about your world and the decisions you make
every day. In living our lives, we're always taking on risks and
exposing ourselves to dangers. We're trying things which we think will
probably succeed, but we're not sure. Probability theory gives you one
them.

In professional life, more people use statistics than any other branch
of mathematics. Experimental scientists use statistics every time they
report their results, to give an indication of the accuracy of their
measurements and the likelihood they may be wrong. Medical researchers
use statistics to establish the likelihood that a drug or treatment
will be effective. Social scientists use statistics to generalize
about people's behavior, and marketers and political surveyers put the
same kind of study to practical use for the benefit their clients.
Insurance companies have a business plan that is entirely based on
their understanding of statistical probabilities; if you think about
it, banks are doing the same thing with their lending, but at risk
levels that they hope are much lower. Every manufacturing company
applies statistical techniques to quality control and customer
satisfaction. The list goes on and on...
