Need help plz: Jill is playing cards with her friend when she draws a card from a pack of 20 cards numbered from 1 to 20 what is the probability of drawing a number that is square

So 1, 4, 9, & 16 are all perfect squares 
Probability = 4/20 = 1/4 = 20% 
                        ^ Either of these could work depending on the problem.
