Is known that
(a + b)² = a² + 2.a.b + b²
So:
(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16
For the answer to the question, <span>what is the probability that he gets a number greater than 2 or an odd number? My answer is
</span><span>all possible rolls are > 2 or odd, except (2), so 5/6
I hope my answer helped you. Feel free to ask more questions. Have a nice day! </span>

B = -9/16 (0.5623)
C = -0.4
D = -5/16 (0.3125)
