Slightly more complicated probability events including compound events. Tree diagrams are used to map out all the possible outcomes and to determine the final probability.
  • How do you know the probability of pulling different colored balls from a bag if you get two picks?
  • What is a tree diagram in probability?
  • How can you use a tree diagram to find probability of a compound event?
  • If a bag has 5 red balls and 3 white balls, what is the chance of picking 1 ball of each color if you replace the first ball?
  • How can you draw a tree diagram to map out possible outcomes?
  • How can you determine the probabilities on the branches of a tree diagram?
  • What does it mean for outcomes to be mutually exclusive in probability?
  • What are some properties of tree diagrams?
  • Why are different paths on a tree diagram mutually exclusive?
  • If a bag has 5 red balls and 3 white balls, what is the probability of picking a red ball on your second pick if you do not replace the first ball?
  • If a bag has 9 blue balls and 7 green balls, what is the probability of picking at least 1 green ball in 2 picks?
This video goes through several examples of probability problems that can be solved easily using a tree diagram. This is a great tutorial for how and why to use tree diagrams to map out possibilities and find the resultant probabilities of events. All steps and calculations are shown for all problems. This is a definite must-watch for learning about tree diagrams.
