Answer 6

Toss a penny, and record whether it comes up heads or tails. Flip the penny in a shoebox to prevent it from rolling away:
What are your chances for tossing a head?
What are your chances for tossing a tail?
Toss the penny 10 times and record the number of times it comes up heads and the number of times it comes up tails:
How many times did you expect to get heads?
How many times did you expect to get tails?
Calculate and record the deviation observed from what you expected using the following formula:


The more the experimental results deviate from the expected results, the more the deviation value will approach the value of 1.0. As your results get closer to the expected results, the deviation is smaller and nears the value of 0.0.

Interpret the meaning of the deviation value you obtained.

Now continue tossing the coin, and record your results until you have tossed the coin 100 times:
How many times did you get heads?
How many times did you get tails?
How many times did you expect to get heads?
How many times did you expect to get tails?
What is the deviation for the 100 tosses?
Repeat the 100-toss trial at least once. Record the total number of heads and tails you obtained from all 100-toss trials:
How many times did you get heads?
How many times did you get tails?
How many times did you expect to get heads?
How many times did you expect to get tails?
What is the deviation for the 200 (or more) tosses?
How does increasing the total number of coin tosses from 10 to 100 affect the deviation?
How does increasing the total number of tosses from 100 to 200 (or more) affect the deviation?
What two important probability principles were established in this exercise?
Now, obtain two pennies. Toss both coins 100 times and record your results:
How many times did two heads occur?
How many times did two tails occur?
How many times did one head and one tail occur?
The percent of occurrence is the obtained results divided by the total tosses and multiplied by 100. Calculate the percent occurrence for each combination:
What is the percent of occurrence for two heads?
What is the percent of occurrence for two tails?
What is the percent of occurrence for one head and one tail?
