The present invention is an electronic learning aid which employs a scanning device for reading printed coded indicia which includes random number modes. A first random number mode provides a flat distribution random number in accordance to a range command. This mode is actuated by scanning coded indicia, firstly, a random number generation command and secondly, a range command. The apparatus then generates a random number from a set of numbers, this set of numbers being determined by the range command. This random number is then employed to select a response which is provided to the user by a speech synthesizer speaking one or more words of human language. In a second embodiment, the random number command enables generation of a random number from among a set in which the probability of selecting one member of the set is different from the probability of selecting other members of the set. This mode could be employed to simulate the number of spots turned upon tossing of two or more dice. As in the first embodiment, the result is communicated to the user via one or more words of human language spoken by a speech synthesizer.
