Answer» Let A: MBA aspirant will join TIM ⇒ P(A) = \(\frac{2}{5}\) B: Will join XLRI ⇒ P(B) = \(\frac{1}{3}\) A ∩ B = 9 ∴ P(Join hI Mor x LRl) = P(A∪ B) = P(A) + (PB) = \(\frac{2}{5}\) + \(\frac{1}{3}\) = \(\frac{11}{15}\) P(Neither llM nor x LRI) = P(A’∪ B’) = P(A∪ B)’ = 1 – P(A∪B) = 1 - \(\frac{11}{15}\) = \(\frac{15 - 11}{15}\) = \(\frac{4}{15}\) |
