## 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
