Answer: d. [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
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 :-
[tex]P=\frac{\text{square numbers}}{\text{total numbers}}\\\\\Rightarrow\ P=\frac{4}{20}=\frac{1}{5}[/tex]
Hence, The probability that the number selected is the square of a natural number is [tex]\frac{1}{5}[/tex]
