**Reiny**, Sunday, October 21, 2012 at 12:41pma) no restrictions, except can't start with a zero

so 8x8x7x6x5 = 13440

b) has to be odd, not start with zero

has to end with odd number, there are 4 of these

can't start with zero, leaving 7 (remember one is already gone in the odd spot)

number of cases = 7x7x6x5x4 = 5880
