You must change from 'round()' to 'floor()'. Otherwise, if a value like 0.84 is rounded with 'round()' to 2 decimal places (0.84 * length = 1.68 -> 2), an index that doesn't exist will be selected. Resulting in an error.

The corrected code would be

let outcomesIndex = Math.floor(Math.random() * outcomes.length);
