As 300 tickets are sold , the probability of being a winner is = 
The prize value is $64 or 
= 0.213
The cost of ticket you paid = $4
Hence, the expected value of one ticket = 0.213-4 = -3.787 or rounding off we get -3.79
Answer:
169
Step-by-step explanation:
You should know that the middle number with the x is double the original number not in expanded form. You should also know that in the expanded form, the last number is the square of the original number. So square(26/2) = 169.
To solve, you'd have to find the area of the big circle(including walk way) and minus the ice rink.
Area of the big circle =

= 7850
Area of ice rink =

= 5024
7850 - 5024 = 2826
The answer is about 2,826 square feet.
