The main property is  as follow

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

I added 3/4 + 1/5 and got 4/9 " does it make sense?
masya89 [10]
<h3 /><h3>\frac{3}{4}  +  \frac{1}{5}  =  \frac{4}{9}  \\  \frac{3 \times 5}{4 \times 5}  +  \frac{1 \times 4}{5 \times 4}  =  \frac{4}{9}  \\  \frac{15 + 4}{20}  =  \frac{4}{9}  \\  \frac{19}{20} ≠ \frac{4}{9}</h3>

THIS SHOWS THAT YOUR ANSWER IS NOT CORRECT.
