What is the probability of more than 8 heads? 4.3 The Hypergeometric Distribution = ) , , ; ( N a n x h -- n N x n a N x a for x = 0,1 2,…. .n x<a; n-x < N-a. 1.Hypergeometric distribution applies to sampling “n” from N without replacement. Bernouilli trials but not independent. 2, Hypergeometric probabilities are approximately equal to b(x; n , a/n) for n<N/10. Example: Three articles are selected from a lot of 10 articles of which 2 are defective and 8 are good by picking one at a time without replacement. Let X denote the number of defectives among the 3 drawn . Determine the probability distribution for X. What are the corresponding values if we sample without replacement?...
