Answer: Expected value = $2.034

Explanation:

Total outcome = 52

Favorable Outcome = 8

Probability of drawing a card with a value of three or less = \frac{Favorable\ outcome}{Total\ outcome}

= \frac{8}{52}

=  \frac{2}{13}

Probability of drawing a card with a value of more than three = 1 -  \frac{2}{13}

=  \frac{11}{13}

Hence,

Expected value = 146 \times \frac{2}{13} + (-24) \times \frac{11}{13}

= 22.338 - 20.304

= $2.034

Lelu [443]

Answer:

Answer is option a, i.e. trade-offs and connections may differ in short run and the long run.

Explanation:

Keynes' law in economics and Say's law in economics are contradictory in their perspective. Where Keynes' law says that it is the demand that creates the supply, on the other hand, Say's law states that its the supply that tends to create the demand. But, we cannot neglect any of the above facts as demand and supply cant operate independently. So, on combining the two laws, we happen to take both the given laws into account. Also, it is found that Keynes' law is more appropriate and accurate for the short-run whereas, Say's law is for the long run. This thus creates trade-offs and connections that differ in the short-run and long-run by affecting the three important goals of macroeconomics, i.e. higher standard of living, low inflation, and low unemployment.
