The number selected is the square of a natural number is 1/5.
What is probability and example?
- Probability = the number of ways of achieving success. the total number of possible outcomes.
- For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .
The square number between 1 and 20 = 1,4,9,16
The number of squares between 1 and 20 = 4
The total numbers between 1 and 20= 20
The probability that the number selected is the square of a natural number is given by -
P = Square number /total numbers
P = 4/20 = 1/5
Therefore, the number selected is the square of a natural number is 1/5.
