We will solve the equation:
x^2+5x-100≥0
x1≈-12.8 x2≈ 7.8
It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).
Answer: C) x ≠ 7
Thank you.

If you spin the dial two times there three things that can happen:
1) Dial does not land in the region A
2) Dial lands once in the region A
3) Dial lands twice in the region A
The combined probability of these three events has to be 1.
Let's calculate probabilities of each event:
If we summ all those probabilities we get 1.
The answer would table C (lower left corner).
