Example question: Tasmin has a bag containing 2 silver tickets and 5 gold tickets. She takes a ticket at random puts it back then takes a second ticket.

To create a probability tree you must first find the variables in the question. In this situation the two variables are the silver and the gold tickets.

Next you would create your probability tree. To do this, you would create two branches. One branch labeled for silver and the other labeled for gold. At the end of the branches you will label the probability of the event happening, in this situation picking a gold ticket.

If you don't know how to continue from there then what the hecc are you doing in advanced.
