a give the probability of getting a sequence of Gold then Silver then Blue on three consecutive spins. b.If the wheel is spun four times, give the probability of getting Blue only on the fourth spin. c.Give the probability of getting at least one Blue on five consecutive spins. there are 4 red spaces, 2 blue, one gold, and one silver space.

Expert Solution

We have a spiinerhaving 4 red spaces, 2 blue, one gold, and one silver space.

Now, let

R: event of getting red in a spin.

B: event of getting blue in a spin.

G: event of getting gold in a spin.

S: event of getting silver in a spin.

a) The probability of getting a sequence of Gold then Silver then Blue on three consecutive spins=

=P(G).P(S).P(B)

b) If the wheel is spun four times,then the probability of getting Blue only on the fourth spin =

=P(not B). P(not B) .P(not B) .P(B)

c) The probability of getting at least one Blue on five consecutive spins=

= P( getting one blue) + P( getting two blue) + P( getting three blue) + P( getting four blue) + P( getting five blue)

There are three light fixtures. 70 bronze; 120 gold; & 35 silver. The common costs for those 225 fixtures was $38,650. Here are some more numbers that production gave me. Gold glass is $2.25 per panel. Bracket is $4.25. Bronze glass is $.75 per panel. Bracket is $3.25. Silver glass is $1.75 per panel and bracket is $2.73. Given the processing sequence, is there a split off point or points? What does that mean? If there is a split off...

A consumer has 10 pounds of gold and 20 pounds of silver. The price of gold ?) = $4,000 a pound while the price of silver ?* = $1,000 a pound. Gold and silver are the only two goods that can be consumed. Write down the budget constraint of this consumer and draw it on a graph. Suppose that the price of silver increases to $2,000 a pound. Draw the new budget constraint. Has the purchasing power of our consumer...

discuss why free coinage of silver (basically allowing silver, in addition to gold, to be used as money) would motivate farmers in the central states of the US to form a protest party that still represents the most significant challenge to the US two party system since the Civil War. Why would farmers in particular be concerned about the money supply? What would be an equivalent demand in today's terms to their demand for coinage of silver?
