Apack of three cards, labeled 1, 2, and 3, is shuffled. william, mary, and anne each
take a card from the pack. each of the two players holding a card with low values
(1 or 2) pays the amount of money appearing on the card he or she is holding to the
player holding the high-valued card (namely, 3). depict this situation as a game in
extensive form.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
