To create a probability tree, we can follow some easy steps. This will help us see all the different results that might happen. Let's go through it step by step:
Identify the Experiment: First, figure out what you are looking at. For example, flipping a coin and rolling a die.
List Possible Outcomes: Think about all the results you can get for each event. When you flip a coin, you can get Heads (H) or Tails (T). When you roll a die, the results can be 1, 2, 3, 4, 5, or 6.
Draw the First Level: Start drawing your tree. For the coin flip, make lines that branch out to H and T.
Draw Subsequent Levels: From each result of the first event, draw lines for the next event. From H, draw lines for each possible die result (1 to 6). Do the same for T.
Label Probabilities: Now, add probabilities to each branch. The chance of getting H is 0.5 (or 50%), and the chance of rolling a 1 is 1 out of 6, which is about 0.17. So, the chance of getting H and rolling a 1 together is 0.5 times 1/6, which equals 1/12.
Calculate Total Probabilities: To find the chances of combined events, just multiply along the branches.
By following these steps, you can easily see the problem and work out the probabilities. Have fun creating your tree!
