Hi, could anyone solve this question by considering some possible cases ?
Thanks in advance!
D?
We don’t know if the numbers are evenly distributes or uniformly distributed or normally distributed
Because we don’t even know if the numbers are integers, practically any number (b/w 0 to 50) can be x and y, the only condition that needs to be satisfied is x > y
eg, x can 48 (there can be 39 numbers after it from 48 -50)
y can be 2 (there can
be 40 numbers b/w 0 and 2, and 20 numbers b/w 2 and 48)
x - y = 48 - 2 = 46
46 > 20
eg 2, x can 27 (there can be 39 numbers after it from 27 - 50)
y can be 23 (there can be 40 numbers b/w 0 and 23, and 20 numbers b/w 23 and 27)
x - y = 27 - 23 = 4
4 < 20
