1.Let 999 distinct balls be distributed among 444 boxes, B1,B2,B3B_1, B_2, B_3B1,B2,B3 and B4B_4B4. If the probability that B3B_3B3 contains exactly 333 balls is k12(93)\dfrac{k}{12} \binom{9}{3}12k(39), then kkk lies in the set:a.{x∈R:∣x−3∣<1}\{x \in \mathbb{R} : |x - 3| < 1\}{x∈R:∣x−3∣<1}b.{x∈R:∣x−2∣≤1}\{x \in \mathbb{R} : |x - 2| \leq 1\}{x∈R:∣x−2∣≤1}c.{x∈R:∣x−1∣<1}\{x \in \mathbb{R} : |x - 1| < 1\}{x∈R:∣x−1∣<1}d.{x∈R:∣x−5∣≤1}\{x \in \mathbb{R} : |x - 5| \leq 1\}{x∈R:∣x−5∣≤1}Login to continueOnly logged in users canattempt or see the solution.
