Calculating Simple Probability

Mathematics · Probability · procedural

Calculate the probability of a simple event with equally likely outcomes using the formula: probability = number of favourable outcomes ÷ total number of possible outcomes; express the result as a fraction in its simplest form; apply to rolling dice, drawing from bags, and other simple chance situations

What mastery looks like

  • Calculate the probability of drawing a blue marble from a bag of 3 blue and 7 red as 3/10
  • Use the formula P(event) = favourable outcomes ÷ total outcomes to solve at least three different problems
  • Explain why increasing the number of favourable outcomes increases the probability

Check your understanding

If there are 3 red and 7 blue balls in a bag, can Calculating Simple Probability work out the probability of picking a red one and express it as a fraction in its simplest form?
