2. Learning Outcomes:
1-Explain probability as a numerical description of the
likelihood of an event.
2-Assign probabilities based on intuition or experience.
3-Estimate probabilities by performing experiments.
3. An impossible event has a 0% •
chance. The chance of a
certain event is 100%. •
Chances can be described
numerically on a scale from 0%
to 100%.
4.
5. Probability is a number between 0 and
1 (inclusive) that
describes the likelihood that an event
will happen. In this section you learned
some ways to assign probabilities—
based on intuition, on history, or on
data from experiments. In the next
sections you will use these ideas to
assign probabilities to some more
complicated events.
