E-Portfolio Strand Maths Probability Term 2 2018

Probability Unit

Learning Outcomes

Level 2

Probability

• Investigate simple situations that involve elements of chance, recognising equal and different likelihoods and acknowledging uncertainty.

Level 3

Probability

• Investigate simple situations that involve elements of chance by comparing experimental results with expectations from models of all the outcomes, acknowledging that samples vary.

Level 4

Probability

• Investigate situations that involve elements of chance by comparing experimental distributions with expectations from models of the possible outcomes.
• Use simple fractions and percentages to describe probabilities.

1) Describe in your own words what these words mean.

Probability - I think probability means a problem to solve or a chance of an event happening.

Impossible - I think impossible means there is no way something can happen e.g. if I asked Robert at Mairehau to ride Pepper it would never happen because she is dead.

Unlikely - I think unlikely means that it could possibly happen but there isn't a big chance e.g. if I asked one of the workers at Mairehau if I could ride Bugs there isn't a big chance of getting him because he is really popular.

Even chance - I think even chance means that there is a 50 50 possibility of you getting something or having something. e.g. there is 4 bottles of coke, 2 of them are diet coke and the other 2 are raspberry I have a 50% chance of getting diet and the other 50% is getting raspberry flavored coke.

Likely - I think likely means there is a higher chance of something happening e.g. it is a really good chance for me to get Sunshine because he is a really experienced horse that barley anyone can ride.

Certain - I think certain means you are defiantly getting something you want e.g. I am defiantly getting another riding lesson at Mairehau soon.
