A number cube with the numbers 1 through 6 is rolled. Find P (number is greater than or equal to 3).
4/6
1/6
2/6
5/6
The numbers greater than or equal to 3 on the number cube are 3, 4, 5, and 6. There are a total of 6 possible outcomes when rolling the number cube.
Therefore, the probability of rolling a number greater than or equal to 3 is 4 out of 6, which can be simplified to 2/3.
So, the correct answer is 2/6.
