In a football or soccer game, you have 22 players, from both teams, in the field. What is the probability of having any two players with the same birthday? (just assume 365 days a year and don’t have to do the exact calendar month and day, use the day number from 1 to 365)
Find the closed form mathematical solution by probability theory. Show your derivation/proof.

Assume an economy with no international sector.
(a) Explain how a decrease in the money supply will affect interest rates.
(b) Explain how the change in the interest rate you identified in part (a) will directly affect each of the three components of aggregate demand for this closed economy.
(c) Explain how the change in the interest rate you identified in part (a) will affect each of the following in the short run.
(i) Output
(ii) Price Level

Evaluate the surface integral
| S |
F · dS
for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation.
F(x, y, z) = x i − z j + y k
S is the part of the sphere
x2 + y2 + z2 = 1
