Relative Frequency Experimental Probability

​​Classroom practice
1.) Be on time to class. Only 5 minutes waiting time is given before the lesson
begins.
2.) Please make sure all your laptops, textbook , notebooks and stationary
sets are with you at all times. You are not allowed to leave the classroom once
you have entered. Strictly no handphones allowed.
3.) Listen to your teacher while she is talking.
4.) Show some respect to your peers when they are answering questions.
5.) Please be on your best behaviour at all times.
6.) Raise your hand if you would like to ask questions, answer or if you would like to use the washroom.
7.) Homework submission
: - Date will be given - Only three warnings - Parents will be contacted
- Always check your google classroom for the summary of the day
- Messy handwritting will not be entertained
- Practice invidual marking or peer markings before the books are being collected.
8.) Keep the class clean at all times and push in the chairs before leaving the classroom.
9.) Last but not least, I am looking forward for good grades
and enjoyable learning environment from all of you.

​Chapter 13.2 : Experimental and Thereotical Probability

​Learning objective :

To design and conduct chance experiments or simulation, using small and large numbers of trials. Compare the experiment probabilities and the theoretical outcomes Success Criteria: Learners can consider different ways of trying to test a conjecture. Learners can stimulate an experiment

​Let's refer to our textbook examples.

Multiple Choice

Probability tells you:

• exactly the number of times an event will happen

• how many times an event is likely to occur

Multiple Choice

The more times you flip a coin the experimental probability of getting tails gets closer to the theoretical probability.

• true

• false

Hani flipped a coin to see if it was biased.

Here are his results. What is the difference between the experimental probability of getting a tail and the theoretical probability?

Give your answer as a fraction in its simplest form.

Fill in the Blanks

Tieje rolled a dice 100 times. The relative frequencies of each score are given in this table. What is the relative frequency for a score of 4 on Tieje’s dice?

Fill in the Blanks

There are four types of counters in a bag, each showing a number from 1 to 4.

The table shows the results of an experiment where a counter was withdrawn and then replaced, and its number recorded.

What is the theoretical probability that the next counter will be a 4? Give an exact answer as a decimal.

Multiple Choice

An experiment was run to collect the result from this spinner.

The most likely results from these options below would be:

• blue = 6,    red = 6,    yellow = 6

• blue = 10,  red = 20,  yellow = 4

• blue = 5,    red = 11,  yellow = 6

• blue = 22,  red = 34,  yellow = 24
