The interval that has the greatest length, will be the most likely interval.
To determine the length of each interval, it may be faster to first convert the fractions to decimals. We get:
A) 0 and 0.15 (interval length = 0.15)
B) 0.15 and 0.2 (interval length = 0.05)
C) 0.2 and 0.25 (interval length = 0.05)
D) 0.25 and 0.3 (interval length = 0.05)
E) 0.3 and 0.5 (interval length = 0.2)
Answer: E
