- A bowl on a dinner table has 10 black olives and 6 green olives. Jaime
stands eats an olive after picking an olive at random from the bowl. He then
picks another olive at random and eats the second olive.
- Draw a tree diagram to represents all the possible outcomes of these
two picks by Jaime.

Use your tree diagram or otherwise and find the probability - that Jaime eats a black olive and a green olive.
- that Jaime eats a black olive first and then a green olive.
- that Jaime eats two olives of the same colour.

- Draw a tree diagram to represents all the possible outcomes of these
two picks by Jaime.
- Edwin was offered a plate with 10 marshmallows, 3 of them were green, 2
blue and 5 red. He picked and ate two marshmallows at random one after the
other.
- Draw a tree diagram to represents all the possible outcomes of these
two picks made by Edwin.

Use your tree diagram or otherwise and find the probability - that Edwin ate a red marshmallow and a green marshmallow.
- that Edwin ate two marshmallows of the same colour.

- Santa has 10 chocolate bars and 35 granola bars in his bag. Nirvan and
Junius are asked to pick an item at random from Santa's bag. Find the probability
that

- the second person in the line will receive a peach

- Albert, Bertha, Cindy, Devi, Enrique, and Fu-Yu are members of Model United
Nations. Two students will be selected from this group to attend a conference
in Geneva.
- With the aid of an appropriate diagram (hints: table of outcomes), find the number of different possible combinations of two students that could attend the conference.
- Find the probability that Devi will be selected for the conference.
- Find the probability that Devi and Enrique will be selected for the conference
