What could be the possible outputs of the following code from the given choices? Why?

import math

import random

a = (math.random()*4) + 10

b = (math.random()*4) + 10

print (a, b)

(i) 0.0101 4.5623

(ii) 10.5678 13.9234

(iii) 11.1234 12.7826

(iv) 0.9238 14.7895



(ii) and (iii) are the possible outputs because:

  • The range  of random( ) is 0.0 to 1.0.
  • When the output is  multiplied with 4 the range becomes 0.0 to 4.0 
  • When 10 is added the range becomes 10.0 to  14.0.
  • So the values of a and b should be between 10.0 to 14.0(where 14.0 is exclusive).
