Answer: The probability is 0.5

Step-by-step explanation:

The probability will be equal to the quotient between the area of region II, and the total area of the board (supposing that the probability of hitting in any place is equal)

The total area of the figure is equal to

Area = (15' + 35')*(8' + 20') = 50'*28' = 1400 in^2

Now, the area of region II is:

Region II = 20'*35' = 700

Then the probability is:

P = 700/1400 = 1/2 = 0.5

$2 {y}^{2} - 9y - 2 + 4(y + 1) =$

$2 {y}^{2} - 9y - 2 + 4y + 4 =$

$2 {y}^{2} - 9y + 4y - 2 + 4 =$

Collect like terms

$2 {y}^{2} - 5y + 2 =$

$(2y - 1 )(y - 2)$
