Question

A student studying for a vocabulary test knows the meanings of 14 words from a list of 22 words. If the test contains 10 words from the study list, what is the probability that at least 8 of the words on the test are words that the student knows?

1 Answer

  • The numerator would be (14c8 x 10c2) + (14c9 x 10c1) + (14c10 x 10c0)┬áDenominator would be like (24c10) ┬áso therefore the answer would be 156156 / 1961256 which equals like, 8%

    If that's wrong, you can blame my girlfriend. Also tell me if it's wrong so I can rub it in her face that she was wrong.
