285. Appraisals of the value of a necklace are uniformly distributed on the interval [θ−3,θ +1], where θ is the actual price the owner paid for the necklace. Four mutually independent appraisals are obtained. Let L denote the lowest of the four appraisals and H the highest. Calculate P[L ＜ θ ＜ H]. (A) 0.152 (B) 0.188 (C) 0.600 (D) 0.680 (E) 0.996
