A group of 20 students have been on holiday abroad and are returning to Norway. In thegroup, there are 7 who have bought too much alcohol on duty-free and none of them informsthe customs officers about it. Customs officers randomly select 5 people from these 20students for control. We let the variable X be the number of students among the 5 selectedwho have bought too much alcohol.(a) What type of probability distribution does the variable X have? Write down the formulafor the point probabilities.(b) What is the probability that none of those checked has bought too much?(c) What is the probability that at least 3 of the 5 controlled students have bought toomuch?

The question is about discrete prob. distribution Given : Total no. of students ( N ) = 20 No. of…

Nine plants are operated by a garment manufacturer. They feel there is a sixteen percent chance for a strike at any one plant and the risk of a strike of a strike at one plant is independent of the risk of a strike at another plant. Let X be the number of plants of the garment manufacturer that strike. Compute the probability that 3 of the plants will strike. Round your answer to four decimal places, if necessary.
