Clifford types this is a typing lesson. he misses the letters o and n in the word lesson. assuming he takes one minute to type the sentence, what is his error rate?

5 errors per minute.

There are 24 characters in that phrase (including full stops and spaces), and 2 of them were incorrect. This means that 1/12 times, he makes a mistake. Multiplying 1 and 12 by 5 (to get an equivalent fraction) is 5/60 - 60 is the number of seconds in a minute. 
Every minute he types, he makes 5 mistakes :D Please correct me if I am wrong, hope I helped!
