Solve this : 29. At a fete, cards bearing numbers 1 to 1000, one number on one card are put in a box. Each player select one 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) second player wins a prize, if the first has won ? E\What values are stimulated, if fete is organised in a society and prizes are distributed ?
22. Two dice are thrown simultaneously. What is the probability that:
(i) 5 will come up on either of them ?
(ii) 5 will come up on atleast one ?
