Question

A card is drawn from a pack of 50 cards numbered 1 to 50. Find the probability of drawing a cube number. [Cube number mean a number multiplied by itself 3 times *

Answer 1

Answer:

A cube number is the result when a number has been multiplied by itself twice. The symbol for cubed is 3.

For example, 8 is a cube number because it’s 2 x 2 x 2 (2 multiplied by itself twice); this is also written as 23 (“two cubed”).

Another example of a cube number is 27 because it’s 33 (3 x 3 x 3, or “three cubed”).

A cube number can also be called a number cubed.

2³ = 2 × 2 × 2 = 8

3³ = 3 × 3 × 3 = 27

4³ = 4 × 4 × 4 = 64

5³ = 5 × 5 × 5 = 125

Answer 2

The probability of drawing a cube number is 18/50
