Answer: The probability of rolling a number not less than 4 on a 6-sided die is 50%.
Step-by-step explanation: To find the probability of rolling a number not less than 4 on a 6-sided die, we need to determine the number of favorable outcomes (rolling a number not less than 4) and divide it by the total number of possible outcomes (the numbers 1 through 6).
Favorable outcomes:
- Rolling a 4, 5, or 6.
Total possible outcomes:
- There are 6 sides on a 6-sided die.
So, the probability of rolling a number not less than 4 is:
P(not less than 4) = Number of favorable outcomes / Total possible outcomes = 3 / 6 = 1/2
To express this probability as a percentage, multiply by 100:
P(not less than 4) = 1/2 * 100% = 50%
So, the probability of rolling a number not less than 4 on a 6-sided die is 50%.
