All of the natural squares from one to twenty are  1,4,9, and 16. This means there is 4 out of 20 which can be reduced to 1 out of 5 or 20%

The probability that the number selected is the square of a natural number will be 0.20.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Robin randomly selects a number between 1 and 20.

Then the total number of the events will be

Total events = 20 {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}

The probability that the number selected is the square of a natural number will be

We know that natural numbers 1, 2, 3, 4, 5, and so on.

Then the square of the natural  numbers will be

1, 4, 9, 16, 25, ....

Favorable event = 3 {1, 4, 9, 16}

Then the probability will be

P = 4 / 20

P = 1/5

P = 0.20

The probability that the number selected is the square of a natural number will be 0.20.
