प्रश्न
A bag contains 100 identical marble stones which are numbered 1 to 100. If one stone is drawn at random from the bag, find the probability that it bears a perfect square number.
उत्तर
Total number of possible outcomes = 100
Numbers which are perfect squares = 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
Number of favorable outcomes = 10
P(a perfect square) = `10/100 = 1/10`
