See, we are told to find the chances of a value lying in between 1 and 0.5
the probability of getting a number in between 1 and 0.5 is 1/50
so we have 50 such numbers to get in between 1 and 0.5
the maximum options we have to select from the more chances we have to get the number in between 1 and 1/2
Going by options:
A values lie in between 1/2 and 13/20
that is 0.5 and 0.65
the probability of getting a number in between 0.5 and 0.65 is 1/15 (15 numbers)
B values lie in between 13/20 and 7/10
that is 0.65 and 0.7
the probability of getting a number in between 0.65 and 0.7 is 1/5 (5 numbers)
C values lie in between 7/10 and 3/4
that is 0.7 and 0.75
the probability of getting a number in between 0.7 and 0.75 is 1/5 (5 numbers)
D values lie in between 3/4 and 4/5
that is 0.75 and 0.8
the probability of getting a number in between 0.75 and 0.8 is 1/5 (5 numbers)
E values lie in between 4/5 and 1
that is 0.8 and 1
the probability of getting a number in between 0.8 and 1 is 1/20 (20 numbers)
The maximum probability of getting a number in between 0.5 and 1 is 20 numbers
because if you select rest options there will be less numbers in the set to select from.
E option have the most numbers we can select from
Hence Answer is E
