No two numbers add up to 3 and multiply to -2
Answer:
Expected Value = - 0.5
Step-by-step explanation:
Expected Value [ E(X) ] = Σ {X. Probability (X)} = Σ [ (X).P(X) ]
Probability = 1 / 1000
X Value = 500 - 1 = 499
Probability = 1 - Probability Winning = 999 / 1000
X Value = -1
(1 / 1000) (499) + (999 / 1000) (-1)
0.499 - 0.999
= - 0.5
The equivalent value of the sum for any value of "x" is 12x - 6
<h3>How to find the sum of functions?</h3>
Given the sum of the expression as:
3
∑ k(2x-1)
k=0
We need to take the sum of the function at the point where k = 0 to 3
3
∑ k(2x-1) = 0(2x-1) + 1(2x - 1) + 2(2x-1) + 3(2x - 1)
k=0
3
∑ k(2x-1) = 2x-1+4x-2+6x-3
k=0
3
∑ k(2x-1) = 12x - 6
k=0
Hence the equivalent value of the sum for any value of "x" is 12x - 6
