Study Notes

Tables of Outcomes

A table of outcomes is a visual method of showing the possible results of two independent events.
The table can be used to find the probability of each possible outcome occurring.
Events are independent if the probability of one event occurring does not affect the probability of the other event occurring.

Constructing a Table of Outcomes

One event's outcomes are displayed vertically, and the other's displayed horizontally.
Each box in the table represents one possible combined outcome.
The table can be used to calculate the probability of each combined outcome.

Calculating Probability

The probability of a particular outcome is the number of target outcomes divided by the total number of outcomes.
The formula to calculate probability is: P = (Number of target outcomes) / (Total number of outcomes)

Example: Rolling Two Dice

Two fair, six-sided dice are rolled at the same time.
The table of outcomes shows the possible results of rolling the two dice.
The probability of each combined outcome can be calculated using the table.

Example: Calculating Probability of a Square Number

Two fair, six-sided dice are rolled at the same time.
The probability of their product being a square number can be calculated using the table of outcomes.
The table of outcomes can be used to identify the target outcomes and calculate the probability.
