Scratch file designed by Linda Fahlberg-Stojanovska.
Our coin is "weighted" so that p(Heads)=0.4 and we toss it 5 times.
In this experiment we have decided that:
Guided Activity 1: 2 out of 5
Do the experiment once by clicking . Do you understand what a winning combination is?
Do the experiment 1000 times by clicking .
Now for some dreaded theory ...
1. An example of a winning combination is TTHHT. What is the probability of getting this combination?
2. Another example of a winning combination is HHTHT. What is the probability of getting this combination?
3. A third example is HTTHH. This combination is "similar to" example 1 or example 2? Why?
Change the weight of getting a heads, click , calculate the theoretical probability and compare your results.
Guided Activity 2: Other Bernoulli* experiments
Example: What is the probability of k=12 or more successes in n=15 trials of a Bernoulli experiment with p=0.72 ?
A Bernoulli or Binomial Trial has exactly 2 events: Success (Win) and Fail (Lose) with p=Pr(Success).

MetaData: CA_APSP_3.0 Students demonstrate an understanding of the notion of discrete random variables by using this concept to solve for the probabilities of outcomes, such as the probability of the occurrence of five or fewer heads in 14 coin tosses.
