KIA ORA !!!!
Today I will be talking about probability the lesson I have been learning since the middle of the term, I also learned so many things in maths, and down below shows what I have learned about probability.
Here are the topics that we did at the start of term 3.
- Location and Navigation
- Bearings
- Grid Reference
- Cartesian Coordinates.
Probability
- Describing chances
- Fractions, Decimals, Percentages
- Basic Probability
- Sample space
- Experimental Probability/ Relative Frequency
- Expected number
There are more topics but the class has done only 6 lessons on probability so I am pretty proud of myself for doing at least that much work I have learned a lot about probability it’s like at the moment we’re learning about the expected number of what expected number it is?
We can calculate the number of times a successful trial is expected to occur given the relative frequency and the total number of trials.
Let’s use algebra to rearrange our original equation:
p(E) = no of successful outcomes / no of trials
Therefore:
no of successful outcomes = p(E) * no of trials
Example: We know that drawing a red marble from our marble bag has an experimental probability of 0.4. If we draw a marble 30 times, how many do we expect to be red?
No successful outcomes = p(E) * no of trials
No successful outcomes = 0.4 * 30
No successful outcomes = 12
