Step-by-step explanation:
The sum of two consecutive even integers is at most seven more than half the sum of the next two consecutive even integers
two consecutive even integers: n, n+2
next two consecutive even integers n+4, n+6
n+(n+2) >= 7+1/2(n+4 +n+6)
combine like terms
2n+2 >= 7 +1/2(2n+10)
distribute 1/2
2n+2 >= 7+n+5
2n+2>= n+12
subtract n from each side
n+2>= 12
subtract 2 from each side
n>10
4 integers : 10, 12 ,14, 16
The probability of drawing both without replacing either is :
14/41 * 12/40 = 7/41 * 3/5 = 21/205
The probability of drawing both WITH replacement is:
14/41 * 12/41 = 168/ 1681
