### Probability

How likely is an event to occur?

What are the chances of that happening??!!

Lesson objectives:
• To understand the terms ‘equal chance’ and ‘outcome’ when thinking about probability.
• To complete a maths investigation involving tossing a coin and rolling a dice!

- to test the ‘equal chance’ theory!

Mathematical Vocabulary
• We can describe the probability or chance of an event happening by saying:
• It is IMPOSSIBLE.
• It is UNLIKELY.
• It is LIKELY.
• It is CERTAIN.
We discussed these:
• If you toss a coin you have an equal chance of getting a head or a tail. Heads or tails are the ‘outcomes’.
• If a baby is born it has an equal chance of being a boy or a girl. Boy or girl are the ‘outcomes’.
• If you roll a dice you have an equal chance of getting the number 1, 2, 3, 4, 5 or 6! These scores are the ‘outcomes’.
• We are going to carry out a maths investigation.
• We are going to investigate whether we have an equal number of heads and tails when we toss a coin 30 times.
• We will also investigate whether we get an equal number of 1s, 2s, 3s, 4, 5s and 6s when we roll a dice 30 times.
• We will record our findings.
What do you think we will find out?
• Perhaps we will have 15 heads and 15 tails when we toss our coin 30 times??
• Perhaps we will have each number on the dice 5 times. (five scores of 1, five scores of 2 etc.)
• It’s up to you to find out!!!!
Did we achieve out learning objectives today?
• We understand what is meant by the terms ‘equal chance’ and ‘outcomes’.
• We have carried out an investigation into ‘equal chance’.
• We have recorded our findings.
