Binomial Distribution
Quick fact
The binomial distribution was first studied by Jacob Bernoulli in the late 1600s, and his work led to the discovery of the Law of Large Numbers.
Why this is interesting
If you flip a fair coin 10 times, what's the probability of getting exactly 7 heads? Intuitively, you might guess it's low, but how low? The binomial distribution gives you the exact answer.
