1.	A bag contains some cards. The numbers 6 – 50 are printed on them. A card is at random drawn from the bag. The probability that the number drawn is a perfect square is:(A) \(\frac { 1 }{ 15 }\)(B) \(\frac { 2 }{ 15 }\)(C) \(\frac { 1 }{ 9 }\)(D) \(\frac { 4 }{ 45 }\)
Answer» Answer is (C) \(\frac { 1 }{ 9 }\) The numbers 6 to 50 are printed on the cards in the bag. ∴ The number of all possible outcomes = 45 The perfect square numbers printed on the cards are 9, 16, 25, 36, 49 The number of favourable outcomes = 5 The required probability = \(\frac { 5 }{ 45 }\) = \(\frac { 1 }{ 9 }\)

Answer»

Answer is (C) \(\frac { 1 }{ 9 }\)

The numbers 6 to 50 are printed on the cards in the bag.

∴ The number of all possible outcomes = 45

The perfect square numbers printed on the cards are 9, 16, 25, 36, 49

The number of favourable outcomes = 5

The required probability = \(\frac { 5 }{ 45 }\) = \(\frac { 1 }{ 9 }\)
