Probability Comparison
Visual comparison of experimental vs. theoretical probability:
When you toss a fair coin, the theoretical probability of getting heads or tails is exactly 50% each. However, in a small number of tosses, the experimental results may vary significantly from this theoretical value. As you perform more tosses, the experimental probability should get closer to 50% for both outcomes.
The Science of Probability
Probability is the branch of mathematics that deals with the likelihood of events occurring. It quantifies how likely something is to happen, ranging from 0 (impossible) to 1 (certain).
For a fair coin:
- Theoretical probability of heads = 1/2 = 50%
- Theoretical probability of tails = 1/2 = 50%
- Experimental probability is determined by actual coin toss results
This fundamental principle states that as the number of trials increases, the experimental probability will approach the theoretical probability. This is why with just a few tosses, you might see 70% heads, but with thousands of tosses, it will be very close to 50%.
Probability concepts are used in:

- Insurance: Calculating risk and premiums
- Medicine: Determining treatment effectiveness
- Sports: Analyzing player and team performance
- Finance: Assessing investment risks
- Gaming: Designing fair games of chance
