If a number cube is rolled what is the probability that the number rolled will be greater than 3?
It is 1/2 if it is a fair number cube which is rolled once.
What is the difference between a cube and a perfect cube?
A cube is any number multiplied by itself three times, eg 2 cubed = 2³ = 2×2×2 = 8; 1.5³ = 1.5×1.5×1.5 = 3.375 A perfect cube is an integer (whole number) that is the cube of an integer, eg 8 is a perfect cube as it is 2 cubed, but 9 is not a perfect cube as 9 = 2.08008382...³
Is 333 a a cube number?
No, 333 is not a cube number. A cube number is an integer that can be expressed as the cube of another integer, such as (1^3 = 1), (2^3 = 8), or (3^3 = 27). The cube root of 333 is approximately 6.9, which is not an integer, indicating that 333 cannot be expressed as (n^3) for any integer (n).
How is 784 a perfect cube?
The number 784 is not a perfect cube. A perfect cube is defined as a number that can be expressed as the cube of an integer (i.e., (n^3) for some integer (n)). The cube root of 784 is approximately 9.24, which is not an integer, indicating that 784 cannot be represented as a whole number cubed.
If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
If a number cube is rolled what is the probability that the number rolled will be greater than 3?
It is 1/2 if it is a fair number cube which is rolled once.
How many outcomes are possible if a number cube is rolled once?
Assuming it is a 6-sided number cube, it would be 6.

Is 77 a cube number?
If by cube you mean perfect cube (a cube of an integer), then no, and the nearest perfect cube is 81.
A 1-6 number cube is rolled what is the probability that the number rolled is a two or a five?
7
Is 83 a cube number?
No, 83 is not a cube number. A cube number is an integer that can be expressed as the cube of another integer (n^3). The cube numbers closest to 83 are 64 (4^3) and 125 (5^3), indicating that 83 falls between these two values and is not itself a cube.
Would 169 be perfect cube or bothor neither?
169 is neither a perfect cube nor a perfect square. A perfect cube is a number that can be expressed as the cube of an integer, and 169 is equal to (13^2) (a perfect square) but not (n^3) for any integer (n). Thus, it does not meet the criteria for being a perfect cube.
Is 400 a cube number?
No, 400 is not a cube number. A cube number is an integer that can be expressed as the cube of another integer, meaning it can be written in the form ( n^3 ). The cubes of integers around ( 400 ) are ( 7^3 = 343 ) and ( 8^3 = 512 ), showing that ( 400 ) falls between these two values and is not a perfect cube.
Is 30 a perfect cube?
No, 30 is not a perfect cube. A perfect cube is a number that can be expressed as the cube of an integer, such as (1^3 = 1), (2^3 = 8), or (3^3 = 27). The cube root of 30 is approximately 3.11, which is not an integer, confirming that 30 cannot be written as the cube of any whole number.
