A country uses bronze coins with denominations of 1 peso, 2 pesos, 3
pesos, and 5 pesos, silver coins of denominations of 2 pesos and 5
pesos, and uses gold coins with denominations of 5 pesos, 10 pesos,
and 20 pesos. Show work.
a ) Find a recurrence relation for the number of ways to pay a bill of n
pesos if the order in which the coins are paid matters
b) How many ways are there to pay a bill of 6 pesos
if the order in which the coins are
paid matters?

A box contains 5 fair coins, 4 coins that land heads with
probability 1/3 , and 1 coin that lands heads with probability 1/4
. A coin is taken from the box at random and flipped repeatedly
until it has landed heads three times. Let X be the number of times
that the coin is flipped and Y be the probability that the coin
lands heads.

5 coins are put in a bag. 2 of the coins are weighted with the
probability of flipping heads being three times as great than the
probability of flipping tails; the remaining coins are fair. One of
these coins is selected at random and then flipped once. What is
the probability that a weighted coin was selected given that heads
was flipped?

Instructions:
1. Get 4 coins, any country, any value, as long as it is
2-sided with heads on one side and tails on the other.
2. Without actually flipping the coins, write down what you
think would be the subjective probabilities of the following
sequences:
A. P(THHT) B. P(TTTT) C. P(THTT)

1.In 2015, the Argentine government purchased 5 million flat
screen televisions (worth 100 pesos each) from a television
manufacturer and then sold them to poor people for 1 peso each. The
poor people would not otherwise have purchased the televisions.
What was the impact on Argentine GDP of the government selling the
televisions to the poor people?a.Unable to determine, since it would depend on whether or not the
televisions were produced by domestic or foreign manufacturers.b.GDP went down by 495,000,000...
