Hi,

How many different five-digit whole numbers may be formed from the digits 1,2,3,4 and 5 

if repeated digits are allowed? 5*5*5*5*5 = 3125 different five-digit whole numbers 

How many of the numbers so formed are greater than 30,000? 

(choice of 3,4 0r 5  for the first digit)   3*5*5*5*5 = 1875  

Note: 0r 3/5 of the 3125 different five-digit whole numbers
