Answer:
D.]
Step-by-step explanation:
We will find the standard deviation and variance:
Variance= E
-[![[E(x)]^{2}](https://tex.z-dn.net/?f=%5BE%28x%29%5D%5E%7B2%7D)
E[x] = 3.462
E[{x}^2]= 31.86
Var(x)= 31.86-(3.462)^2 = 28.4
Standard deviation = 
= 
= 5.833 = 6(aproximately)
Therefore, the chances of winning are equal in each lane.
<h2>Answer: </h2><h2>x > 8</h2><h2>~</h2><h3>To solve for X, isolate the variable 'x' by dividing each side by factors that don't contain the variable 'x'.</h3><h3>Inequality Form:</h3><h3>x > 8</h3><h3>Interval Notation:</h3><h3>(8,\infty) or (8, ∞)</h3><h2>~</h2>
