A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number

less than 3. Find the probability of not rolling a number less than 3
A. 1/3;2/3
B. 1/2;1/2
C. 5/6;1/2
D.1/6;5/6

What was the answer?

A thanks i always go to this web site

1/3;2/3

Correct! The probability of rolling a number less than 3 is 1/3, since there are only 2 possible outcomes: rolling a 1 or rolling a 2, out of a total of 6 possible outcomes. The probability of not rolling a number less than 3 is 2/3, since there are 4 possible outcomes that are greater than or equal to 3: rolling a 3, 4, 5, or 6, out of a total of 6 possible outcomes. Well done!

I'll be glad to check your answer.

To find the probability of rolling a number less than 3, we need to count the number of favorable outcomes and divide it by the total number of possible outcomes.

In this case, the favorable outcomes are rolling a 1 or a 2. So there are 2 favorable outcomes.

The total number of possible outcomes is 6, since there are 6 numbers on the cube.

Therefore, the probability of rolling a number less than 3 is 2/6, which simplifies to 1/3.

To find the probability of not rolling a number less than 3, we subtract the probability of rolling a number less than 3 from 1.

So, 1 - 1/3 = 2/3.

Therefore, the answer is A. 1/3; 2/3.

Right.
