Randomness is really important in experiments that use statistics. It helps make sure that the results we get are fair and trustworthy.
Here’s how randomness works:
Sample Space: This is just a fancy term for all the possible outcomes. For example, if you flip a coin, the sample space is {Heads, Tails}.
Events: An event is any group of results from the sample space. For example, if you get Heads, that’s one event.
Probability: Randomness helps us figure out how likely each outcome is. We can calculate the probability (or chance) of an event happening. For example, the probability ( P ) can be found using this formula: [ P(E) = \frac{\text{Number of good outcomes}}{\text{Total outcomes}} ]
Overall, randomness makes experiments more valid. It allows us to make predictions about bigger groups based on what we find in our smaller tests.
