What is most probable chance for four digit numbers have 7 as their first digit and 7 as their last digit?
They first has a greater probability. This is because the first digit comes from a set of 9: {1,2,3,4,5,6,7,8,9} while the second comes from that same set AND 0.
What are the most frequent 3 digit numbers between 0 to 9?
There are no 3 digit numbers between 0 and 9 because 0 and 9 are 1 digit numbers.
How many significant figures does 13.60 have?
4 Every digit between the leftmost non-zero digit and EITHER the right most non-zero digit OR the rightmost digit after a decimal.
What is the period of a 5 digit number?
The period of a 5 digit number comes between the ones place and the tenths place. If there is no period, it is assumed to come to the right of the right-most digit. That would make it a whole number. For example, 1256.9 is one thousand, two hundred fifty six and nine tenths. 3.4582 is three and four thousand, five hundred, eighty two ten thousandths.
What is the three digit number that is greater than 10 and less than 20 whose tens digit is an odd number?
There cannot be a proper three digit number between 10 and 20. It must be a two digit number. If you consider a 2-digit number between 10 and 20, then its tens digit MUST be 1 and so MUST be odd. So most of this question is either wrong or irrelevant. Are you sure you have not cut and pasted bits from two questions?
