Nobel Laureates. From Wikipedia and the article "Which Country Has the Best Brains?" from BBC News Magazine, we obtained a frequency distribution of the number of Nobel Prize winners. by country.
Suppose that a recipient of a Nobel Prize is selected at random. Find the probability that the Nobel Laureate is from
(a) Sweden.
(b) either France or Germany.
(c) any country other than the United States.
Find.
Identify one reason why the complementation rule is useful.
Suppose that a simple random sample is taken from a finite population in which each member is classified as either having or not having a specified attribute. Fill in the following blanks.
(a) If sampling is with replacement, the probability distribution of the number of members sampled that have the specified attribute is a distribution.
(b) If sampling is without replacement, the probability distribution of the number of members sampled that have the specified attribute is a distribution.
(c) If sampling is without replacement and the sample size does not exceed % of the population size, the probability distribution of the number of members sampled that have the specified attribute can be approximated by a distribution.
Construct a venn diagram that portrays four events A, B ,C and D that have the following properties: Events A, B and D mutually exclusive: events A,B and D are mutually exclusive: no other three of the four events are mutually exclusive
