The question is ambiguous.Does it want the sum of the squares, or the square of the sum ? They're different.Here are both:1). Sum of the squares: . (1)2 + (2)2 + (3)2 + (4)2 + (5)2 = 1 + 4 + 9 + 16 + 25 = 552). Square of the sum: . (1 + 2 + 3 + 4 + 5 )2 = (15)2 = 225
Sum = -5 - 3 - 2 + 14 = 4 Count = 4 So mean = Sum/Count = 4/4 = 1
With 2 dice, there are 36 outcomes Of those, a sum of 5 can be made in 4 ways (1 + 4, 2 + 3, 3 + 2, 4 + 1) ⇒ pr(5) = 4/36 = 1/9 ≈ 0.11 ≈ 11 %
The sum of all numbers between 1 and 5 is infinite.The sum of whole numbers between 1 and 5 is 2 + 3 + 4 = 9
5,6,2,3,9 has a greater sum than 10,4,5,1 and 2 which has a sum of 22.
