Question

A card is drawn from a packet of 100 cards numbered 1to 100 . Find the probability of drawing a number which is a square

​

Answer 1

no of square numbers = 10

1² 2² 3² 4² 5² 6² 7² 8² 9² 10²

1 , 4 ,9 25 , 36 ,49 , 64 ,81 ,100

total no of cards =100

P(square numbers) = 10/100

=1/10

Answer 2

Answer:

The probability is 0.1 or you can also say 10%.

Step-by-step explanation:

Square numbers between 1 to 100: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100

So we can see that there are 10 square numbers between 1 to 100.

Probability = No. of outcomes/ Total number of possible outcomes

                  = 10/100 = 1/10 = 0.1 = 10%
