Probability Tree Diagrams
Calculating probabilities can be hard, sometimes we add them, sometimes we multiply them, and often it is hard to figure out what to do ... tree diagrams to the rescue!
Here is a tree diagram for the toss of a coin:
probability branch, probability and outcome
There are two "branches" (Heads and Tails)
The probability of each branch is written on the branch
The outcome is written at the end of the branch
We can extend the tree diagram to two tosses of a coin:
probability tree 2 tosses of coin
How do we calculate the overall probabilities?
We multiply probabilities along the branches
We add probabilities down columns
probability tree calculations (multiply and add)
Now we can see such things as:
The probability of "Head, Head" is 0.5×0.5 = 0.25
All probabilities add to 1.0 (which is always a good check)
The probability of getting at least one Head from two tosses is 0.25+0.25+0.25 = 0.75
