The document outlines a lesson plan to teach students the difference between independent and dependent events and how to calculate the probability of each. The lesson will begin with explaining the key concepts, then provide examples to illustrate the difference between independent and dependent events. Students will have opportunities to ask questions and practice calculating probabilities of independent and dependent events.

4. Next, show the students how to find the probability of a
dependent event.
5. Have the students practice several problems.

4. ❖Two events are independent events if
the occurrence of one event does not
affect the probability of the occurrence
of the other event.

5. ❖Two events are independent events if
the occurrence of one event does not
affect the probability of the occurrence
of the other event.
❖Two events are dependent events if
the occurrence of one event does affect
the probability of the occurrence of the
other event.
