<h3><u>Probabilities</u> </h3>

Given that a bag contains 1 blue, 2 green, and 2 red marbles, and you choose a marble with one hand and then a second marble with the other hand, to determine what is the probability that you will first choose a red marble followed by to green marble the following calculation must be made:

  • 1 + 2 + 2 = 5
  • 2/5 x 2/4 = X
  • 0.4 x 0.5 = X
  • 0.2 =X
  • 0.2 x 100 = 20

Therefore, the probability that you will first choose a red marble followed by a green marble is 20%.
