Answer:

x^4 - 3x^2 - 4.

Step-by-step explanation:

Imaginary roots  occur as conjugate pairs  so a 4th roots is -i.

So in factor form we have:

f(x) = (x - 2)(x + 2)(x - i)x + i)

     = (x^2 + 1)(x - 2)(x + 2)

     = (x^2 + 1)(x^2 - 4)

      = x^4 - 3x^2 - 4.

NONE. You loose. The question says a “FAIR” number cube, so by definition, NONE of the sides comes up MOST often. It’s an invalid QUESTION! Indeterminate Answer.

If it’s a FAIR die, then any of the 6 numbers has the same chance of coming up: 1/6

So, there is no MOST LIKELY result for 100 rolls.
