EastWind [94]

Answer: - 0.027

Step-by-step explanation:

Win = any even number between (0 - 36)

Therefore,

Lose = any odd number between 0 —36 including 0

Assume Bet amount = $1

Expected value is calculate by summing all possible outcomes by their respective probabilities.

Expected value = [(p(winning) × net win value) + (p(losing +net loss value]

P(winning) = p(even) = 18/37

P(losing) = p(odd) +p(0) = 19/37

Net win value = $2

Net loss value = $-1

Expected value = [(18/37) × ($1) + (19/37) × (-$1)]

Expected value = 0.48648648 - 0.51351351

Expected value = - 0.027

atroni [7]

Answer: b. 30%

Step-by-step explanation:

  • A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. CV=\dfrac{\sigma}{\mu}

Given: mean =  \mu=90

Variance = \sigma^2 = 729

\sigma=\sqrt{729}=27

Now, CV=\dfrac{27}{90}=0.3

in percent , CV= 0.3\times100\%= 30\%

Hence, correct option is  b. 30%.
