Question:

If John is 3 feet north of a tree and Phillip is 4 feet south of the same tree, what is the total distance between John and Phillip?

Answer:

Since John and Phillip are on opposite sides of the tree, the distance between them is the sum of their distances from the tree. So, the answer is 3 feet + 4 feet = 7 feet.

Question:

In a bag, there are 60 marbles: 27 red, 19 blue, and 14 green. What is the probability that a marble drawn at random will be blue or green?

Answer:

The probability that the marble will be blue or green is the sum of the probabilities of the two independent events of the marble is blue and the marble being green. Therefore, the probability is 19/60 + 14/60 = 33/60 or 0.55.
