Question 878493
<pre>
This is a binomial probability problem. Where there are 

n = 2954 trials (resumes)
p = 10% = .1 = the probability that if you picked just 1 resume it would have
 spelling errors.
q = 100%-10% = 1-.1 = .9 = the probability that if you picked just 1 resume it
would not have any spelling errors.

r = 296 = the number of "successful" cases you want the probability of.

Watch this video https://www.youtube.com/watch?v=P3ZpHlzWnMs
and use your numbers instead.

Correction factor:
you will use 296.5 for (a) since it WILL NOT include 296

You will use 295.5 for (b) since it WILL include 296

For (c) just subtract the answer for (a) from the answer to (b) 

Watch some more of those videos on youtube. And you can ask me
any questions you have in the thank you note and I'll be glad to
answer by email.  No charge.  I do this as a hobby.
