Walt: assign probabilities to simple events using fractions and percentages.

Today I was learning to assign probabilities to a game played with 2 10 sided dice. I played the game with my friend, Mya. We alternated rolling the dice. We rolled the dice 20 times and we recorded our score in the outcomes column. From the 20 attempts,only twice we managed to get multiples of 6. The probability as a simple fraction is 2/20 and as a percentage it is 10%. Since we worked on similar games this week I now have a better understanding of assigning probabilities. Next time I would like to learn how to find a prime number while assigning probabilities.

Kia ora Alicia,

I like how you edited the paragraph and made it fit to your liking, it's also a bit interesting to read. I as well made a post about my maths which also was linked with probability. I had to find out whether my outcome was a prime number. Did you enjoy doing this little activity?

Malo e lelei Alicia,
I really enjoyed reading your paragraph about what you learned so far this week. I also learned to assign probabilities to simple events using fractions and percentages. My Prediction was to get a multiple of 2 and 3, and I was successful 14 times out of 20. What did you like learning about probability?
