Well the probability of rolling a six on it would be 1/20.
So, if you're rolling it 1,000 times, 1,000 x 1/20 = 50.
You would roll a six approximately 50 times.
You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is

which is in the geometric sequence format. So the answer is choice D
<span>12.6≤<span>g+17.4</span></span> Flip the equation.<span><span> g+17.4</span>≥12.6</span> Subtract 17.4 from both sides.<span><span><span> g+17.4</span>−17.4</span>≥<span>12.6−17.4</span></span><span> g≥<span>−4.8</span></span> Answer: <span>g≥<span>−<span>4.8</span></span></span>
