In a probability experiment, Craig rolled a six-sided die 57 times. The die landed on a number greater than three 33 times. What is the ratio of rolls greater than three to rolls less than or equal to three?
There were 33 rolls that were greater than 33. Since there were 57 rolls altogether, there were 57-33 = 24 rolls that were not greater than 33; they must be less than or equal to 33. Thus the ratio is 33:24.
