can be formed using the digits 0,1 and 5​

Answer 1

Answer:

2

Step-by-step explanation:

150 , 510

Answer 2

Answer:

I will assume that the numbers can be repeated such that 1 and 5 may each occupy any one of the three possible digit positions. Since the resulting numbers must be three digits, there cannot be leading zeroes and therefore the 0 can only occupy any of the two digit positions (tens and units).

Therefore the possible number of 3 digit numbers will be 3 x 3 x 2 = 18
