Joey had 40 words to study for a spelling quiz, but he only learned 10 of them. His teacher surprised the class by telling them that the quiz would only have 1 of those 40 words on it. If the teacher chose that 1 word randomly, what is the probability that it was one of the words Joey learned

The probability of choosing a word randomly which is   one of the words Joey learned = 1/4

Step-by-step explanation:

Total number of words to be memorized = 40 words

The number of words memorized  by Joey = 10
