A jar contains 100 marbles.
20 of the marbles are red.
40 of the marbles are blue.
The rest of the marbles are green.
A marble is randomly selected from the jar.
Work out the probability that the marble is green.
Answer:
Total marbles = 100
Green marbles = 100 – 20 – 40 = 40
Probability= 40 / 100 = 0.40
