Answer:
Fair game
Step-by-step explanation:
Let us find the sample space. It is the sum of the two spins
1+1 1+2 1+3 1+4 1+5 1+6
2+1 2+2 2+3 2+4 2+5 2+6
3+1 3+2 3+3 3+4 3+5 3+6
4+1 4+2 4+3 4+4 4+5 4+6
5+1 5+2 5+3 5+4 5+5 5+6
6+1 6+2 6+3 6+4 6+5 6+6
Adding
2,3,4,5,6,7
3,4,5,6,7,8
4,5,6,7,8,9
5,6,7,8,9,10
6,7,8,9,10,11
7,8,9,10,11,12
P(2) = 1/36
p(3) = 2/36
p(4) = 3/36
p(5) = 4/36
p(6) = 5/36
p(7) = 6/36
p(8) = 5/36
p(9) = 4/36
p(10) = 3/36
p(11) = 2/36
p(12) = 1/36
Player A wins if the sum is even
P(2,4,6,8,10,12) = P(2)+P(4)+P(6)+P(8)+P(10) + P (12) because the events are independent
= 1/36 + 3/36+5/36+5/36+3/36 +1/36= 18/36 = 1/2
Player B wins if the sum is odd
P(3,5,7,9,11) = P(3)+P(5)+P(7)+P(9)+p(11) because the events are independent
= 2/36 + 4/36+6/36 +4/36+2/36= 18/36 = 1/2
The probabilities are the same, so this is a fair game
To solve this problem simplify 9/2 widgets to 4.5. Next, multiply that number by 6. (1/6*6=I full hour).
The answer is 27.
