If one of the factors of the number 3728173 is randomly chosen, then the probability that the chosen factor will be a perfect square is
Explanation:
Number of factors of 3728173 = (7 + 1)(8 + 1)(3 + 1) = 8 × 9 × 4 = 288
Number of factors of 3728173 which are perfect squares = (4)(5)(2) = 40
Required probability = 40/288 = 10/72 = 5/36.
Hence, option (a).
