A number cube with the numbers 1 through 6 is rolled. Find the given probability.
P(number ≥3)
A.) 4/6
B.) 1/6
C.) 2/6
D.) 5/6
Out of the six faces of the numbered cube, three faces have numbers less than 3 and three faces have numbers greater than or equal to 3.
The probability of rolling a number greater than or equal to 3 is therefore 3/6 or 1/2.
So, the answer is (C) 2/6.
To find the probability of rolling a number that is greater than or equal to 3 on the number cube, we need to determine the number of favorable outcomes and the total number of possible outcomes.
There are three favorable outcomes: rolling a 3, 4, 5, or 6.
The total number of possible outcomes is six, since there are six numbers on the number cube.
Therefore, the probability is the number of favorable outcomes divided by the total number of possible outcomes.
P(number ≥3) = 3/6 = 1/2
So, the correct answer is not provided in the options.
To find the probability of getting a number greater than or equal to 3 when rolling a number cube (also known as a fair six-sided die), you need to determine the number of possible outcomes that fit the criterion and divide it by the total number of possible outcomes.
In this case, there are four numbers (3, 4, 5, and 6) that are greater than or equal to 3.
The total number of possible outcomes when rolling a number cube is 6, as there are six sides numbered 1 through 6.
Therefore, the probability of getting a number greater than or equal to 3 is 4 out of 6.
So, the correct answer is A.) 4/6.
