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

A motor boat travels in a straight line across a river which flows at 3ms–1 between straight parallel
banks 200 m apart. The motor boat, which has a top speed of 6ms–1 in still water, travels directly from
a point A on one bank to a point B, 150m downstream of A, on the opposite bank. Assuming that the
motor boat is traveling at top speed, find, to the nearest second, the time it takes to travel from A to B.

here i am wid anther wierd question!!
