The 'Survey'

We chose (by computer) a random number between 0 and 100.

The number selected for you is X = [65 / 10]

  1. Do you think X is greater or less than the percentage of countries that are in Africa?
  2. Write down your best estimate of the percentage of countries that are in Africa.
  3. How many children does your mother have (including you)?
  4. How many children does your oldest aunt have?
