+function randomWholeNum() {
+
+  // Only change code below this line.
+  Math.floor(Math.random() * 10);
+  return Math.floor(Math.random());
+}
+```
+
+We need to use ```Math.floor()``` with ```Math.random()``` to generate and return a random whole number between 0 and 9.
+Putting ```Math.floor()``` and ```Math.random()``` together, this is what our code looks like:
+
+```javascript
+Math.floor(Math.random() * 10);
+```
+
+And we need change the value of ```return```:
+
+```javascript
+return Math.floor(Math.random());
+```
+
+Here’s a full solution:
+
+```javascript
+var randomNumberBetween0and19 = Math.floor(Math.random() * 20);
+
+function randomWholeNum() {
+
+  // Only change code below this line.
+  Math.floor(Math.random() * 10);
+  return Math.floor(Math.random());
+}
+```
