dude they asking number above 3000 so it must be 3,4,5,6
how can it be 1,2,3???
just think!!
astarmathsandphysics:
How many different 4-digit numbers greater than 3000 can be formed using the six digits
1, 2, 3, 4, 5 and 6 if no digit can be used more than once?
toxic dude or ne body answer this!!!
saw ms
it said 4*(5*4*3)
explain why??
the first number has to be one of 3,4,5,6
5 choices for the 2nd number
4 choices for the 3rd
and 3 choices for the 4th
hence4*5*4*3
as soon as the first number is picked you only a have a coice of 5 etc
