The probability that the answer choice which Rohit selects for a question is wrong is 2/3
<h3>What is the probability that the answer choice which rohit selects for a question is wrong?</h3>
The given parameters are
Options = 3
Correct Option = 1
The above means that
Wrong options = 2
The probability that the answer choice which Rohit selects for a question is wrong is calculated as:
P = Wrong options/options
So, we have
P = 2/3
Hence, the probability that the answer choice which Rohit selects for a question is wrong is 2/3

Answer:
25.5in²
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = (1/2) x (sum of the lengths of the parallel sides) x height
1/2 x (6 + 11) x 3 = 25.5 in²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Roots at x=-10 and x=-8
if a function has roots at x=r1 and x=r2, then the factored form is
f(x)=a(x-r1)(x-r2) where a is a constant
so
roots -10 and -8
f(x)=a(x-(-10))(x-(-8))
f(x)=a(x+10)(x+8)
now
use (-9,-3)
-3=a(-9+10)(-9+8)
-3=a(1)(-1)
-3=-a
3=a
the equation is
y=3(x+10)(x+8)
or expanded
y=3x²+54x+240
