Morse code is used to send messages. Each symbol is represented by a series of dots and dashes. Would a maximum of four dots and/or dashes be sufficient?

"Yes"

Explanation:

"We have 2 possibilities : dots and dashes."
"This means that a series of n dots/dashes yields "2^n" "combinations."
"So if we let n go from 1 to 4 we have : "2^1 + 2^2 + 2^3 + 2^4
=30 " possible symbols."
"The alphabet is 26 letters, so we have 4 symbols left for"
"punctuation."
"I don't know what is done with digits 0,1,2, ...,9 though."
