Probability and the Lottery in Layman's Term probability-and-the-lottery | 页面 8

As you see, the yellow marbles outnumbered the five red marbles.
Probability explains that when you randomly pick a marble from a jar with
your eyes closed, you will more likely get a yellow one.
Your second and third pick will be more likely yellow marbles again because
the probability leans towards the yellow marbles getting picked more often
than the red ones.
In mathematics, we express the probability of the two types of marbles in the
following ways:
P(yellow) = 95/100 or 95%
P(red) = 5/100 or 05%
Assuming we reset the number of marbles in each trial, the yellow marbles
will get picked 95 times in every 100 draws. Then the black marbles will
only get picked 5x in every 100 draws.
The same probability principle rules in a random game such as the lottery.
Let me give you some theoretical proofs in the next pages that in fact
combinations in the lottery exhibit different probabilities.
