For Maths this week we have been learning to make tree diagrams. For this we had to choose two pieces of data to use, I chose one about chocolate and one about marbles, the questions were, Marbles: A bag contains 3 black balls and 5 white balls. Paul picks a ball at random from the bag and replaces it back in the bag. He mixes the balls in the bag and then picks another ball at random from the bag. Calculate the probability that Paul picks: two black balls a black ball in his second draw
Chocolate: Maria is buying 3 bars of chocolate to share with her friends. There are 3 different bars of chocolate for her to choose from: moro bar, crunchie, picnic. How many different possibilities are there? What is the probability that she gets a moro & a crunchie? After we did this we had to put the data onto a tree diagram and answer the questions. Here are the tasks:
Do you know how to make tree diagrams?
