Question: There are 19 books on Geography, 16 books on Zoology and 20 books on Math in a bundle of books. Three books are selected one after the other. Find P(book on Zoology, book on Geography, no book on Math). A ) 2 321 B ) 152 2385 C ) 1 160 D ) 912 15125 Steps to derive 1 P(first book on Zoology) = N u m b e r o f b o o k s o n Z o o log y T o t a l n u m b e r o f b o o k s = 16 55 2 P(second book on Geography) = N u m b e r o f b o o k s o n G e o g r a p h y N u m b e r o f b o o k s r e m a i n i n g = 19 54 3 As the third book should not be a Math book, it should be selected from the remaining 18 Geography books or 15 Zoology books.4 P(no book on Math) = 33 53 5 P(book on Zoology, book on Geography, no book on Math) = P(book on Zoology) × P(book on Geography) × P(no book on Math) [Substitute and simplify.]7 = 16 55 × 19 54 × 33 53 = 152 2385 Hence the right answer is Option B Click Here To Go Back Few Other Questions - Write the amplitude of y = 5sin(x4)...
