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 number divisible by 4.
उत्तर
Total number of possible outcomes = 100
Numbers which are divisible by 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100
Number of favorable outcomes = 25
P(number divisible by 4) = `25/100 = 1/4`
