Consider an experiment that consists of recording the birthday for each of 20 randomly selected persons. Ignoring leap years, we assume that there are only 365 possible distinct birthdays. Furthermore, we assume that each of the possible sets of birthdays is equi-probable (1)What is the probability that each person in the 20 has a different birthday?(2)Find the minimum number of persons such that the probability of two or more people have a same birthday is at least 50%.(3)Find the minimum number of persons such that the probability of two or more people have a same birthday is at least 95%

The SoftDrink Company must decide whether or not to introduce a new diet drink. Management feels that if it does introduce the diet soda it will yield a profit of $1 million if sales are around 100 million, a profit of $200,000 if sales are around 50 million, or it will lose $2 million if sales are only around 1 million bottles. If the company does not market the new diet soda, it will suffer a loss of $400,000. An internal marketing research study has found P(100 million in sales) = 1/3; P(50 million in sales) = 1/2; P(1 million in sales) = 1/6. ShouldSoftDrink introduce the new diet soda?
