Question 689191
A student studying for a vocabulary test knows the meanings of 16 words from a list of 24 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?
-------
Binomial Problem with n = 10 ; p(know) = 2/3
----
P(8<= x <=16) = 1-P(0<= x <=7) = 1 - binomcdf(16,2/3,7) = 0.9500
