Mathematics (2019) Grade(s): 8 - Grade 8 Accelerated

Students know:

Possible relationships and differences between the simple probability of an event and the probability of an event under a condition.

Students are able to:

Accurately determine the probability of simple and compound events.
Accurately determine the conditional probability P(A given B) from a sample space or from the knowledge of P(A&B) and the P(B).

Students understand that:

Conditional probability is the probability of an event occurring given that another event has occurred.

Example: the probability of drawing a king from a deck of cards, given that it is a face card, is $\frac{4/52}{12/52}$, which is $\frac{1}{3}$.
