Question

21. Read the following passage and answer the following questions

fete cards bearing numbers 1 to 1000, one number on one card, are put in a box. Each player selects
card at random and that card is not replaced. If the selected card has a perfect square greater than
500, the player wins a prize. What is the probability that
(i) the first player wins a prize?
(ii) the second player wins a prize, if the first has won?
​

Answer 1

Answer:

Step-by-step explanation:

total nos=1000

consider the perfect square nos between 500-1000

the outcomes favourable are=23^2;24^2;25^2;26^2;27^2;28^2;29^2;30^2,31^2

1.thus,no of favourable outcomes=9

P(E)=9/1000

2.the card is not replaced;the total no of outcomes=999

given that the first player has won

so; the no of favourable outcomes=8

thus, the probability of the second player wins = 8/999
