From the given information,
P(blue) = 45/60 = 3/4
P(yellow) = 10/60 = 1/6
P(green) = 5/60 = 1/12
Probability compares good outcomes to all possible outcomes; odds compares good outcomes to other outcomes. Since P(green) = 1/12, P(not green) = 11/12, and so the odds of arriving when green are 1/12 : 11/12, or 1:11
NOTE: usually (but not always) probabilities are expressed in the form a/b (or as an equivalent percentage), while odds are usually expressed in the form a:b
ANSWERS:
probability of arriving when blue = 3/4
odds of arriving when green = 1:11
