Consider the following game, called matching pennies, which you are playing with a friend. Each of you has a penny hidden in you
Dahasolnce [82]

Answer:

a. The two players playing the game

b. No dominant strategy

c. No equilibrium

Step-by-step explanation:

a. The players are the two people playing the game of matching pennies

The strategy of the players are to meet the conditions of them keeping the pennies by having either heads or tails

The payoff of the game are as follows;

Player A keeps the two pennies when the outcome matches

Player B keeps the two pennies when the outcome does not match

The payoff of the game are as follows;

                                                Player A

                                             Head                          Tails

Player B  Head                     1, -1                              -1, 1

               Tails                      -1   1                               1, -1

Where:

x, y

x = Player A

y = Player B

1 = Getting to keep the two pennies

-1 = Losing a penny

b. There are no best strategy because the game is one of chance whereby the result of the strategy of one player depends on the side of the penny facing up by the other player.

c. There is no equilibrium as the possible outcomes are equal hence the outcomes can be even or one sided.

Why is 751, 447 rounded to 800,000
disa [49]
I believe its because anything above 5 is rounded up, 7 rounded up is 8 and how I was taught is if its a number (this case its 751,447) the 7 in it would round to 8 causing all the other numbers to go up as well causing the 800,000 >.< I

6(x+1)/5=5x-3 help please?
Korolek [52]
First, multiply each side by 5

6(x+1) = 25x-15

distribute the 6

6x+6=25x-15

put the x's on the same side and the other numbers on the opposite side

21=19x

Divide by 19 to isolate the x

21/19=x
