Romi has a collection of 10 distinct books out of which 8 are small and 2 are large. In how many ways can he select 5 books to take with him on a trip if he can take at most 1 large book?
Since Romi can take at most 1 large book then he can take with him either 5 small books or 4 small books and 1 large book: C^5_8+C^4_8*C^1_2=56+140=196.
thanks a lot for your priceless help...
meanwhile could you give alternative way to solve with no formula? cause im just a beginner and it a bit hart to me to keep with formulas
thanks a lot
