Final answer:
The probability of rolling a number less than 4 on a fair 666-sided die is 3/666, which simplifies to 1/222.
Step-by-step explanation:
The probability of rolling a number less than 4 on a fair 666-sided die is calculated by considering the favorable outcomes to the total possible outcomes. In this case, the numbers less than 4 are 1, 2, and 3, which gives us three favorable outcomes. Therefore, the probability (P) of rolling a number less than 4 is P(roll less than 4) = number of favorable outcomes / total number of outcomes = 3/666, which simplifies to 1/222.
Answer choice B) P(roll less than 4) = 3/666 is correct.
