Question

jill is playing cards with her friend when she draws from a pack of 20 cards numbered from 1 to 20. What is the probability of drawing a number that is square

Answer 1

The probability of drawing a number that is square is \frac{1}{5}

Given : jill is playing cards with her friend when she draws a card from a pack of 20 cards numbered from 1 to 20.

To find : What is the probability of drawing a number that is square

\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}Probability=

Total number of outcome

Favorable outcome

Total number of outcome = 20

Square numbers between 1 to 20 is 1,4,9,16

Favorable outcome of (drawing a number that is square) = 4

\text{Probability}=\frac{4}{20}Probability=

20

4

\text{Probability}=\frac{1}{5}Probability=

Therefore, The probability of drawing a number that is square is \frac{1}{5}
