Altmann- Wiring up the Brain
o Neurons send impulses to their connected neurons, the rate at which impulses are
send corresponds to the "strength" of the signal.
o An impulse can make it more likely that another neuron will generate a

MATH 314 POP QUIZ 1 SOLUTION
Suppose a point (X, Y ) is chosen uniformly at random from the square with vertices (4, 0),
(0, 4),(4, 0) and (0, 4).
(1) Find the joint pdf fX,Y .
(2) Compute P r(Y X + 2).
