Jeff types a sentence “she wore a dress yesterday.” he erroneously typed w instead of e for dress. what is the accuracy of the typed sentence? a) 96.6% b) 90% c)1% d) 75.4%

A

Explanation:

Since there are 26 characters and only one of them is incorrect, you would get 1/26. You want 100 as a denominator since we are working with percents. To make the denominator 100, we need to mulitply both the denominator and numerator by 4. That would give us 4/104. Since 106 is very close to 100, we can leave it at that. After that, we need to look at the numerator. The numerator, 4, shows the percent she got wrong. However, since we're looking for accuracy, we need to subtract 4 from 100. That gives us 96. Even though no answer is 96, number A is very close. That gives us letter A. Sorry it wasn't that understandable. Anyway, hope it helps :).
