Final answer:
The probability of rolling a number less than 6 on a 6-sided die is 5/6 or approximately 0.8333.
Step-by-step explanation:
To find the probability of rolling a number less than 6 on a 6-sided die, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
In this case, the favorable outcomes are the numbers 1, 2, 3, 4, and 5, which is a total of 5 possible outcomes.
The total number of possible outcomes is 6, since there are 6 sides on the die.
Therefore, the probability of rolling a number less than 6 is 5/6 or approximately 0.8333.
