Answer.      [C]
Solution.      Probability: probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Total number of cases = 100
prime number from 1 to 100 = 2, 3, 5, 7, 9, 11, 13, 17, 19,
23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 83, 89, 97
Total prime numbers from 1 to 100 = 25
Probability of getting prime number = \frac{prime\, no.\, from\, 1\, to\, 100}{Total\, number}

\\=\frac{25}{100}\\\\=\frac{1}{4}
