Printed circuit cards are placed in a functional test after
being populated with semiconductor chips. Suppose that there are 8
blue credit cards, 6 red credit cards and 4 blue debit cards in a
box. It is known that color and card type are to be independent
when a card is selected at random from this box.
a) How many red debit cards must be present?
b) Suppose that, 5 cards are randomly selected in a row
without replacement. What is the probability that 3 blue credit
cards and 2 blue debit cards are selected?
c) Suppose that, 5 cards are randomly selected in a row with
replacement. What is the probability that 3 blue credit cards and 2
blue debit cards are selected?

Please do not use this as an example: Suppose a company printed
baseball cards. It claimed that 30% of its cards were rookies; 60%
were veterans but not All-Stars; and 10% were veteran
All-Stars.
When evaluating a chi-square test, describe the importance of
the goodness of fit test. Provide an example and explain how the
test is used to evaluate the data.

A laptop assembly is subjected to a final functional test.
Suppose that defects occur at random in these assemblies, and that
defects occur according to a Poisson distribution with parameter λ=
0.03.
What is the probability that an assembly will have exactly one
defect?
What is the probability that an assembly will have one or more
defects?
What is the probability that an assembly will have no more than
three defects?

Suppose that you randomly draw one card from a standard deck of
52 cards. After writing down which card was drawn, you replace the
card, and draw another card. You repeat this process until you have
drawn 15 cards in all. What is the probability of drawing at least
8 diamonds?
