Question

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?

Answer 1

The ratio is 33:24 which would simplify to 11:8.

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.
