1.) 15p4 = start with 15 come down 4 factors: 15*14*13*12 = 32760   
2.) 9p3 = start with 9, come down 3 factors: 9*8*7 = 504
3.) 10c4 = NUMERATOR = start with 10 come down 4 factors
           DENOMINATOR = start with 4 come down 4 factors = %2810%2A9%2A8%2A7%29%2F%284%2A3%2A2%2A1%29 = cancel and multiply = 210
