So there you go, when in doubt draw a tree diagram, multiply along the branches and add the columns. You can see more uses of tree diagrams on Conditional Probability. One final step: complete the calculations and make sure they add to 1: (When we take the 0.6 chance of Sam being coach and include the 0.5 chance that Sam will let you be Goalkeeper we end up with an 0.3 chance.)īut we are not done yet! We haven't included Alex as Coach:Īn 0.4 chance of Alex as Coach, followed by an 0.3 chance gives 0.12.Ġ.3 + 0.12 = 0.42 probability of being a Goalkeeper today

#BLUETECH PROBABILITY TREE HOW TO#
Here is how to do it for the "Sam, Yes" branch:

This is done by multiplying each probability along the "branches" of the tree. The tree diagram is complete, now let's calculate the overall probabilities. If you get Alex, there is 0.3 probability of being Goalie (and 0.7 not): Now, if you get Sam, there is 0.5 probability of being Goalie (and 0.5 of not being Goalie): The probability of getting Sam is 0.6, so the probability of Alex must be 0.4 (together the probability is 1) First we show the two possible coaches: Sam or Alex: So, what is the probability you will be a Goalkeeper today? about 6 out of every 10 games (a probability of 0.6). with Coach Alex the probability of being Goalkeeper is 0.3.with Coach Sam the probability of being Goalkeeper is 0.5.You are off to soccer, and love being the Goalkeeper, but that depends who is the Coach today: That was a simple example using independent events (each toss of a coin is independent of the previous toss), but tree diagrams are really wonderful for figuring out dependent events (where an event depends on what happens in the previous event) like this example: The probability of getting at least one Head from two tosses is 0.25+0.25+0.25 = 0.75.All probabilities add to 1.0 (which is always a good check).The probability of "Head, Head" is 0.5×0.5 = 0.25.We multiply probabilities along the branches.How do we calculate the overall probabilities? We can extend the tree diagram to two tosses of a coin: The outcome is written at the end of the branch.The probability of each branch is written on the branch.

There are two "branches" (Heads and Tails) Here is a tree diagram for the toss of a coin:

Calculating probabilities can be hard, sometimes we add them, sometimes we multiply them, and often it is hard to figure out what to do.
