Find the probability of each event and multiply them together.

Answer 2

would I use a probability calculator? or how do I go about this?

Answer 3

For the first event, you want orange.
What is

(number of orange)/(total number) ?

Answer 4

First event:
p(orange) = (number of orange)(total number) =

Second event:
p(green) = (number of green)/(total number) =

Overall event:
p(orange then green) = p(orange) * p(green)
