Two students devised a game called “3 Pennies & 2 Nickels.” Each player will choose to play the pennies or the nickels. In each round, the players will flip all their coins on the table and record how many heads and tails they have. The table below includes the point scheme.

Alyssa wants to play the game. Choose the statement below that is correct in all aspects.

E(penny) = –0.33 and E(nickel) = 0.33, so she should play with the nickels.
E(penny) = 0.5 and E(nickel) = 1.5, so she should play with the nickels.
E(penny) = 1.75 and E(nickel) = 1.5, so she should play with the pennies.
E(penny) = 2.38 and E(nickel) = 2, so she should play with the pennies.

Ok, let's start by finding the payout of choosing pennies
The chances of getting all pennies on heads or tails is 1/8. What is the chance of getting both a head and a tail?

Answer 5

25%?

Answer 6

Wait...let me think about this xD

Answer 7

okay haha

Answer 8

Ok lol.
----Pennies----
All heads: 12.5%
All tails: 12.5%
One of each: 75%

----Nickels----
All heads: 25%
All tails: 25%
One of each: 50%

Can you write an equation?

Answer 9

well i can tell you she should play with nickels because of the higher chance

Answer 10

(-2)(.125)+(3)(.75)+(-2)(.125)=E(pennies)
=-.25+2.25-.25
=1.75
(-2)(.25)+(5)(.50)+(-2)(.125)=E(nickels)
=-.50+2.50-.50
=1.50

Answer 11

E(penny) = 1.75 and E(nickel) = 1.5, so she should play with the pennies.
