Deductive Reasoning--
It is a logical reasoning that starts with a general set of premises or statements and reach to a specific conclusion.
It is different from the inductive reasoning in the way that the inductive reasoning starts with a set of specific set of rules and reach to a general conclusion.
Answer:
a)![- \frac{1}{19}](https://tex.z-dn.net/?f=%20-%20%5Cfrac%7B1%7D%7B19%7D)
b) SD(x) = 0.9986
Step-by-step explanation:
Given data:
Number of slots 38
slots for red ball 18
slots for black = 18
slots for green 2
outcomes Red Black or Green
Profit 1 -1
P(X) 18/38 20/38
Expected value of wining,
![E(x) = 1. \frac{18}{38} + (-1) \frac{20}{38} = - \frac{2}{38} = - \frac{1}{19}](https://tex.z-dn.net/?f=E%28x%29%20%3D%201.%20%5Cfrac%7B18%7D%7B38%7D%20%2B%20%28-1%29%20%5Cfrac%7B20%7D%7B38%7D%20%3D%20-%20%5Cfrac%7B2%7D%7B38%7D%20%3D%20-%20%5Cfrac%7B1%7D%7B19%7D)
B) Standard deviation of winning SD(x)
![SD(x) = \sqrt{(1- (-\frac{1}{19})^2 .\frac{18}{38} + (1- (-\frac{1}{19})^2 .\frac{20}{38}}](https://tex.z-dn.net/?f=SD%28x%29%20%3D%20%5Csqrt%7B%281-%20%28-%5Cfrac%7B1%7D%7B19%7D%29%5E2%20.%5Cfrac%7B18%7D%7B38%7D%20%2B%20%281-%20%28-%5Cfrac%7B1%7D%7B19%7D%29%5E2%20.%5Cfrac%7B20%7D%7B38%7D%7D)
![SD(x) = \sqrt{\frac{360}{361}](https://tex.z-dn.net/?f=SD%28x%29%20%3D%20%5Csqrt%7B%5Cfrac%7B360%7D%7B361%7D)
SD(x) = 0.9986
