Tree Diagrams

This week we have been learning to use tree diagrams to identify all possible outcomes.  This is part of probability.  Here is my tree diagram showing all sandwich possibilites from these few ingredients.  I found tree diagrams easy to make and you can eassily see all the outcomes.  They can take a long time though.

What's in the news this week?

Kia ora,  today we did current events quiz which we do every Thursday or friday.  One of the questions was about how the Ministry of  Conservation is doing a new trial  with their new project where they will release a big drone to try and track down the predators to try and keep control of pests in New Zealand. They are going to do 3 tests with it and hope it will be ready for full use in 2022.  It cost $790,000. My opinoin is that its not going to work and its going to end up like 1080 and its going to be the best what is your opinoin.
