Question

A box contains cards numbered 11 to 123. A card is drawn at random from the box. Find the probability that the drawn card is a square number

Answer 1

Answer:

we know that p(e)=no. of favourable outcomes /total no. of possible outcomes.

Step-by-step explanation:

There are 8 prefect square numbers 16,25,36,49,64,81,100,121.

total cards are 62

hence probability is 8/62 that is 4/31.

Answer 2

Answer:

Heyaa♡♡

Squar no. between 11 to 123:- 16,25,36,49,64,81,100 and 121.

Favourable outcomes :- 8

Now, By theorical part ( Just for reference don't need to show it in your answer) :-

No. between 1 to 3:- 1, 2, 3

Total no. :- 3

Writing it in Formula :- 3 - 1 + 1 = 3

Now, no. between 5 to 10:- 5, 6, 7, 8, 9, 10

Total no. :- 6

Writing it in Formula :- 10 - 5 + 1 = 6

So, total cards :- 123 - 11 + 1 = 113

It's probability :-

$\frac{no.of \: favourable \: outcomes}{total \: outcomes} \\ = > \frac{8}{113}$

Hope it helped you.
