Probabilities

Given that in Hypothetical Town, the probability that a teenager in a household has an Android device is 0.67 and the probability that a teenager in a household owns an Apple device is 0.33, to determine, if a family has two teenagers, the probability that the family has 0, 1, or 2 teenagers who own an Apple device, the following calculation must be performed:

  • 0.67 x 0.67 = 0.44
  • 0.67 x 0.33 x 2 = 0.44
  • 0.33 x 0.33 = 0.11
  • 0.44 + 0.44 + 0.11 = 0.99

Therefore, the probability that the family has 0 teenagers who own an Apple device is 44.44%, the probability that it has 1 is 44.44% and the probability that it has 2 is 11.11%.
