There can be no number with an odd sum of 8 because 8 is not odd!

∙ 11y agoThe sum of any four odd numbers will never be equal to an odd number.
The probability is 21/36 = 7/12
21 is an odd composite number
this would be explained on the basis of two FACTS below....... sum of two odd numbers are always even and sum of to even numbers are also always even then how 6 odd numbers (consider 3 pairs, 9 5 3 1 being odd numbers) can make an odd number 21..!! SO SIMPLE Make your basics strong...
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.

It is 21 because 21+23 = 44

10/21 First, observe that for the sum of the three balls to be odd, either one is odd and two are even, or all three are odd. Since the sum of two odd numbers is even, the sum of two even number is even, and the sum of an even number and an odd number is odd. P(exactly one is odd)=(5/9)*(4/8)*(3/7)*3=180/504=5/14 P(all three are odd)=(5/9)*(4/8)*(3/7)=60/504=5/42 P(sum is odd)=5/14+5/42=15/42+5/42=20/42=10/21, which is approximately .48
It is 23 because 17+19+21+23 = 80
63 / 3 = 21The middle number is 21The odd numbers next to 21 are 19 and 2319 + 21 + 23 = 63
Start by dividing 44 by 2 to get 22. Therefore, 22 + 22 = 44. If we subtract 1 from one number, and add 1 to the other number, the sum will be the same, but now using two consecutive odd numbers; ie, 21 + 23 = 44. Therefore, the smaller number is 21.
