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
Natasha2012 [34]

Answer:

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

Let E: Event of randomly choosing a  word that Joey has learned.

P(E)  = \frac{\textrm{The total words learned by Joey}}{\textrm{Total Words in the quiz}}

\implies P(E)  = \frac{10}{40}  = \frac{1}{4}

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