Answer:
1/216 or 0.0046
Step-by-step explanation:
Rolling a '1' one time has a probability of 1/6. Rolling a die three times and getting a '1' each time is an independent event, meaning that no roll affects the probability of a '1' happening on any other roll. When calculating probability of independent events, multiply them together. So the probability of a '1' three times in a row is...
(1/6)(1/6)(1/6) = 1/216 or 0.0046
