That people benefit from experience potential failure
Answer:
Low oxygenated areas are called hypoxia.
Low oxygenated waters are called anoxic waters which is a more severe condition of hypoxia.
Minimum probability is 0.05, so we have to choose n such that expected frequency corresponding to 0.05 probability should be at least 5.
Let n = 5
Expected frequency = n*p = 5 * 0.05 = 0.25 < 5
Let n = 25
Expected frequency = n*p = 25 * 0.05 = 1.25 < 5
Let n = 50
then
Expected frequency = n*p = 50* 0.05 = 2.25 < 5
Let n = 100
then
Expected frequency = n*p = 100* 0.05 = 5 = 5
Thus, for n = 100, we get expected frequency = 5,
Thus, the minimum number of times the spinner should be spun to conduct this test is 100.

The ways that are required to prevent fire include:
- Accessible equipment.
- Proper disposal.
- Regular maintenance.
- Safe storage.
It should be noted that it's essential to make all fire protection equipment easily accessible. There should also be proper disposal of hazardous wastes.
Furthermore, there should be regular maintenance of fire equipment. Flammable materials and chemicals should be safely stored too.
In conclusion, having a clean environment is vital because flammable materials like paper can spread fire quickly.
