I spell them correctly.
The number 30 is "thirty" and 31 is "thirty-one."
The factors of all the numbers 1 through 30 include all the numbers 1 through 30.
The two perfect numbers between 1 and 30 are: 6, 28
The sum of whole numbers 1 through 30 is 465.
that is not even close to a question 6 occures in first 30 numbers for just 1 time so probabability of 6 in 30 numbers= 1/30

one
English
(30 + 1) * 30/2 ie 465
The even numbers between 1 and 30 are:2,4,6,8,10,12,14,16,18,20,22,24,26, and 28.
Of the numbers from 1 to 30, only 30 has all three of those numbers as factors.
