Question

Cards marked with number 3,4,5,.... 50 are placed in a box and mixed thoroughly. A card is drawn at rendom from the box find the probability that the selected card bears a prefact square numbers.

Answer 1

Total Number of Cards= 50-2=48
The perfect square number between 3-50 are-4,9,16,25,36,49= 6 perfect squares.
Probability= Number of Perfect squares/Total number of cards
=6/48

Answer 2

Answer:

The probability that the selected card bears a perfect square number is $\frac{1}{8}$

Step-by-step explanation:

Given : Card marked with 3,4,5..........50 are placed in a box and mixed thoroughly. A card is drawn at random from the box.

To find : The probability that the selected card bears a perfect square number?

Solution :

Card marked with 3,4,5..........50

Total number of cards = 50-2=48

Now,  

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

Favorable outcome(a perfect square number) :  4,9,16,25,36,49

So, Favorable outcome = 6

Total number of outcome = 48

$\text{Probability}=\frac{6}{48}\\\\\text{Probability}=\frac{1}{8}$

Therefore, The probability that the selected card bears a perfect square number is $\frac{1}{8}$
