<span>18/n = 60%/100% </span>
<span>18/n = 3/5 </span>
<span>Cross Multiply Then Divide... </span>

<span>18*5/3 = n </span>
<span>to get n = 30 </span>

<span>You could find out 1% = 18 ÷ 60 = 0.3 </span>
<span>100% = 100 x 1% = 100 x 0.3 = 30 </span>

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
