D: 1/6
3 answers
D: 1/6
can u explain why?
Sure!
A standard number cube has 6 faces, each numbered 1 through 6. The probability of getting a 4 or a 5 can be found by adding the probability of getting a 4 to the probability of getting a 5.
The probability of getting a 4 is 1/6, since there is only one face with a 4 out of the 6 faces total.
The probability of getting a 5 is also 1/6, since there is only one face with a 5 out of the 6 faces total.
Adding these probabilities together, we get:
1/6 + 1/6 = 2/6
Simplifying this fraction, we get:
2/6 = 1/3
So the probability of getting a 4 or a 5 is 1/3, making answer choice C correct.
