+// Multiplying Math.random() by (maximum - minimum + 1) scales the random decimal to a range of 0 (inclusive) to 100 (exclusive).
+// The Math.floor() rounds down the number to the nearest whole number, giving us an integer between 0 and 99.
+// Adding minimum (which is 1) shifts the range from 0-99 to 1-100.
