Question

At a fete, cards bearing numbers 1 to 1000, one number on one card, are put in a box.
One card is drawn at random. What is the probability that the selected card is a perfect
square greater than 500?

Answer 1

Answer:

(i) 0.009

(ii) 0.008

Step-by-step explanation:

Total no. of cards = 1000

No. of cards having perfect squares greater than 500 in the set = 9

Probability =  $\frac{No. of favorable events}{ Total no. of possible events}$

HENCE FOR THE FIRST PLAYER WE HAVE,

(i) Probability of the first player to win = 9/1000 = 0.009

(ii) The card is not replaced, hence the total no. of possible choices for 2nd player is 999. Also, it is considered that first player wins. Hence the no. of favorable events is 8.

Probability that the second player wins = 8/999 = 0.008
