Simple Probability
total ways a specific outcome will happen
Probability =
total number of possible outcomes

Example: There are 87 marbles in a bag and 68 of them are green. If one marble is chosen, what is the probability that it will be green?

    Solution
  • Divide the number of ways to choose a green marble (68) by the total number of marbles (87)
  • 68 ÷ 87 = 0.781609
  • Round to the desired precision (e.g. 0.781609 rounded to hundredths is 0.78)
