Out of 10 white, 9 black and 7 red balls, in how many ways
can we select one or more balls
please with solution.
Answer Posted / vanya
The previous answer(s) overlook the possibility that 0 balls can be selected from any color (i.e. 11,10, and 8 choices respectively), as long as all three numbers aren't zero. So it's:
(10+1)*(9+1)*(7+1) - 1 = 879
