--description--

k defects are randomly distributed amongst n integrated-circuit chips produced by a factory (any number of defects may be found on a chip and each defect is independent of the other defects).

Let p(k,n) represent the probability that there is a chip with at least 3 defects. For instance p(3,7) ≈ 0.0204081633.

Find p(20\\,000, 1\\,000\\,000) and give your answer rounded to 10 decimal places in the form 0.abcdefghij

--hints--

chipDefects() should return 0.7311720251.

assert.strictEqual(chipDefects(), 0.7311720251);

--seed--

--seed-contents--

function chipDefects() {

  return true;
