Two dice are tossed. Let X be the smaller number of points. Let Y be the larger number of points. If both dice show the same number, say, z points, then X = Y = z. Find the joint probability mass function of (X, Y).
A 3 micro coulomb charge is uniformly distributed on a ring of radius 11 cm. The value of the Coulomb constant is 8.99 × 109 N · m2/C2. Find the electric field on the axis at 0.9 cm from the center of the ring.
