Step-by-step explanation:
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
Volume=length*width*height (for a rectangular prism)
Plug in the values.
4 1/4*3*1 1/4= the volume
4 1/4*3= 12 3/4, so:
12 3/4 * 1 1/4 is correct as well.
The answer you checked is the correct answer.
I hope this helps!
