solong [7]

Answer:

a) $- \frac{1}{19}$

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,

$E(x) = 1. \frac{18}{38} + (-1) \frac{20}{38} = - \frac{2}{38} = - \frac{1}{19}$

B) Standard deviation of winning SD(x)

$SD(x) = \sqrt{(1- (-\frac{1}{19})^2 .\frac{18}{38} + (1- (-\frac{1}{19})^2 .\frac{20}{38}}$

$SD(x) = \sqrt{\frac{360}{361}$

SD(x) = 0.9986
