Computer Voice Recognition Software Is Getting Better

question 17

Multiple Choice

Computer voice recognition software is getting better. Some companies claim that their software correctly recognizes 98% of all words spoken by a trained user.
To simulate recognizing a single word when the probability of being correct is 0.98, you could use random digits as follows:

• A) Two digits simulate one word; 00 to 97 mean "correct."
• B) Two digits simulate one word; 00 to 98 mean "correct."
• C) One digit simulates one word; 0 to 9 mean "correct."
• D) Three digits simulate one word; 001 to 098 mean "correct."
