Hi, please see the homework policy for assignment related questions.

For the first question, rewording it as

generate three numbers divisible by 5 from random numbers between 100 and 500.

No three random integers are guaranteed to contain at least one occurrence of `x%%5 = 0`

.

The second question is similar in the sense that `each character`

might be ambiguous. Does it mean `each character in the alphabet`

or `each character in X`

? As to `frequency`

, think of it as the number of a particular object in a group of objects divided by the total number of objects in the group.
