Question

After many studies, a researcher finds thatthe probability that a word-recognitionprogram correctly interprets a hand-writtenword is 10. How many words out of40 would the researcher expect theprogram to correctly interpret?

Answer 1

Given:

The probability that a word-recognition the program correctly interprets a hand-written word is:

`=(9)/(10)`

Find-:

How many words out of 40 would the researcher expect the program to correctly interpret?

Explanation-:

the probability that a word-recognition the program correctly interprets a hand-written word is:

`=(9)/(10)`

For 40 world is:

`\begin{gathered} =(9)/(10)*40 \\ \\ =9*4 \\ \\ =36 \end{gathered}`

So, there are 36 words.
