A number cube with the numbers 1 through 6 is rolled. Find P (number is greater than or equal to 3).
a.) 4/6
b.) 1/6
c.) 2/6**********
d.) 5/6
Don't you have 4 chances of rolling a 3, 4, 5, or 6?
To find the probability of rolling a number greater than or equal to 3 on a number cube, we need to determine how many favorable outcomes there are and divide it by the total number of possible outcomes.
In this case, the favorable outcomes are the numbers 3, 4, 5, and 6. There are a total of 4 favorable outcomes.
The possible outcomes are the numbers 1, 2, 3, 4, 5, and 6. There are a total of 6 possible outcomes.
So, the probability (P) of rolling a number greater than or equal to 3 is given by:
P = favorable outcomes / total outcomes
P = 4 / 6
Simplifying the fraction, we get:
P = 2 / 3
Therefore, the correct answer is option c.) 2/6.
