Customs officials are checking a bottle with tablets of a shady person. That person actually put 7 candies together with 5 narcotic tablets of identical appearance. They randomly pick out 3 of the tablets. 1. State the appropriate distribution together with its parameters. 2. What is the expected number of narcotic tablets. 3. What is the formula to find the probability that at least 2 narcotic tablet is picked out.

Step 1
The appropriate distribution for this scenario is the hypergeometric distribution. The parameters for the hypergeometric distribution are: - N: the total number of tablets in the bottle (12 in this case) - K: the number of narcotic tablets in the bottle (5 in this Show more…
