A single standerd number cube is tossed what is the proability of getting a 4 or a 5? A:1
B: 1/5
C: 1/3
D: 1/6
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.
To find the probability of getting a 4 or a 5 when tossing a standard number cube, you need to determine the number of favorable outcomes (getting a 4 or a 5) and divide it by the total number of possible outcomes.
In this case, a standard number cube has 6 faces numbered 1 to 6. Since we are only interested in the outcomes of 4 or 5, there are two favorable outcomes.
So, the probability of getting a 4 or a 5 is 2 out of 6, or 2/6. However, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2.
2/6 simplifies to 1/3.
Therefore, the correct answer is C: 1/3.
