Events Per Second
Now suppose we flip a coin every millisecond
To keep the same event rate, use a constant
Define λ (lambda) in units of heads per second
λ = p * n = heads per flip * flips per second
To increase n to 1,000 flips per second while keeping the event rate the same at
λ = 1 / 60 heads per second,
the probability p would need to be adjusted to
p = λ / n = ( 1 / 60 ) / 1,000 = 1 / 60,000
