Answer:
c. fall in the short run, and fall even more in the long run.
Explanation:
The aggregate demand shifts to the left in recession or contractions, in consequence the level of prices falls. For this analysis we consider the shor-run supply curve with a positive slop.
As we know, the economy in the long run tends to equilibrium, where the the production level is fixed and equal to the potential of production of the economy. The initial reduction of prices incentives the consumption in the long run, stabilizing with the long run quantites in a minor level of prices.

Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
