2) a) find a solution of the differential equation: df (xaf (x) 0 obeying the boundary condition f(xo) =a (hint: use one (and only one! ) exponential function as a trial function b) qualitatively sketch how re[f(x)] from (2.a) looks like for negative real a. make a similar graph for a imaginary, with im(oa) = a > 0 (assume that a, x, xo are positive real numbers). draw the sketches by hand, i. e. think for yourself, do not rely on your graphing calculator! also, mark the salient features of the graph, such as values at special points, etc. 2

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
