You can estimate the deadliness of each type of cancer by dividing the number of deaths by the number of cases. Of nearly everyone who received a diagnosis of one particular type of cancer dies, the ratio will be near 1 (or 100% deadly). If many more people receive a diagnosis than die, the ratio will be near 0 (or 0% deadly). Rank these three cancer types from the most deadly to the least deadly.
