The number will most likely be between the largest range.

A. 0 and 3/20 --> range 3/20;
B. 3/20 and 4/20 --> range 1/20;
C. 4/20 and 5/20 --> range 1/20;
D. 5/20 and 6/20 --> range 1/20;
E. 6/20 and 10/20 --> range 4/20.

Answer: E.

I converted the fractions to decimals and checked the range.

A) 0 and 0.15 > 0.15
B) .15 and 0.2 > 0.05
C) 0.2 and 0.25 > 0.05
D) 0.25 and 0.3 > 0.05
E) 0.3 and 0.5 > 0.2

E covers the largest range. Hence the ans is E.

the answer should be E, since the larger range the larger probability of choosing a number from that range
