Keisha’s basketball team must decide on a new uniform. The team has a choice of black shorts or gold shorts and a black, white, or gold shirt.
Use a tree diagram to show the team’s uniform choices.
a) What is the probability the uniform will have black shorts?
b) What is the probability the shirt will not be gold?
c) What is the probability the uniform will have the same-coloured shorts and shirt?
d) What is the probability the uniform will have different-coloured shorts and shirt?
In pairs, on a whiteboard, create the tree diagram for the following problem (use a second whiteboard to show answer to probability questions)
Brit goes out for lunch to the local submarine sandwich shop. He can choose white or whole wheat bread, and a filling of turkey, ham, veggies, roast beef, or salami. Use a tree diagram to show all Brit’s possible sandwich choices.
Use the tree diagram to answer the following questions
a) How many sub choices are there?
b) He may also choose a single topping of tomatoes, cheese, or lettuce. Now, how many
possible sub choices does he have?
c) If each possibility has an equal chance of selection, what is the probability that Brit will
choose a whole wheat turkey sub topped with tomatoes?
d) What is the probability of choosing a veggie sub topped with cheese?
e) What is the probability of choosing a meat sub topped with lettuce on white bread?
f) What is the probability of choosing a meat sub topped with lettuce?
