Probability:
Probability is such a native part of your life that you rarely think about it. Though, every time you use a word like “might,” “may,” “undoubtedly,” “without fail,” or “maybe,” you can see and even a probability that an event will occur.
Scientists and great mathematicians like to express probability more accurately. For example, if you toss a coin in the air, the probability (P) that it will land heads or tails.
Materials Required:
A book and a pencil.
Four coins.
Procedure:
Using a paper and pencil, draw circles with an “H” or a “T” in the center of the paper to illustrate the different results when you toss these three coins.
Using the circles that you drew as mentioned above, express the following:
The probability of getting three heads while tossing the coins.
The probability of getting three tails while tossing the coins.
The probability of getting one head and three tails while tossing the coins.
The probability of getting one tail and three heads while tossing the coins.
Hint: There are eight distinctly different possibilities so make sure you haven’t left any of them out.
Try tossing three coins 16 times and writing down the outcomes. Are the probabilities roughly equal as you calculated in step 2? Try tossing three coins 24 times. Are the probabilities any closer?
