WebWe can con rm the Law of Total Probability for Expectations using the data from the previous example. 4.7 Conditional Expectation 257 The value of E(Y x)will not be uniquely deÞned for those values of xsuch that the marginal p.f. or p.d.f. of X satisÞes f 1(x)=0. However, since these values of x WebThe third box has nine bulbs, out of which two are dead. Find the probability of selecting a dead bulb randomly from one of the three boxes. Solution. Total number of boxes = 3. The number of boxes from which the bulbs will be chosen = 1. Probability = P (B_i) = Total number of bulbs in the first box = 12. Number of dead bulbs = 5 harbor freight trailer hitch basket
