Calculating Probabilties

Level 3

• I can find all possible outcomes using a table, list or tree.
• I can describe probabilities using words.
• I understand why experimental probabilities may be different to theory.

Level 4

• I can find find all possible outcomes using a table, list or tree for simple one and two stage situations.
• I can use simple fractions and percentages to describe probabilities.
• I recognise that different trials in a probability experiment may lead to different estimates as outcomes are random.
• I have an understanding of independence.
