Step-by-step explanation:
The odds are 4 to 1 against, so we can estimate the probability of success (p) as
The expected pay for every success is 3 to 1, so we lose $1 for every lose and we gain $3 for every win.
The number of winnings in the 100 rounds to be even can be calculated as:
We have to win at least 25 rounds to have a positive payoff.
As the number of rounds is big, we will approximate the binomial distribution to a normal distribution with parameters:
The z-value for x=25 is
The probability of z>1.25 is
P(X>25)=P(z>1.25)=0.10565
There is a 10.5% chance of having a positive payoff.
NOTE: if we do all the calculations for the binomial distribution, the chances of having a net payoff are 13.1%.

Step-by-step explanation:
The reportable square footage for Kinsey's home = 2150square feet.
The main floor of Kinsey's home is 1,425 square feet.
The upper level is 875 square feet with one unfinished bedroom that measures 150 square feet.
The finished basement is 1,425 square feet with 7.5-foot ceilings.
That means the square footage of the upper floor plus the main floor (minus the unfinished laundry area).
Kinsey should report square feet (1425+875- 150)
= 2150square feet.
Hence, The reportable square footage for Kinsey's home = 2150square feet.
