Wires go between Boston, Chicago, and Seattle. Those cities are at voltages
xB, xC, xS.
With unit resistances between cities, the three currents are in y:
y=Ax is ⎡⎣⎢yBCyCSyBS⎤⎦⎥=⎡⎣⎢101−1100−1−1⎤⎦⎥⎡ ⎣⎢xBxCxS⎤⎦⎥.
(a) Find the total currents
ATy
out of the three cities. (b) Verify that
(Ax)Ty
agrees with
xT(ATy)
six terms in both.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
