+# --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`.
+
+```js
+assert.strictEqual(chipDefects(), 0.7311720251);
+```
