In a probability experiment, Craig rolled a six-sided die 64 times. The die landed on a number greater than three 39 times. What is the ratio of rolls greater than three to rolls less than or equal to three? A.

B.

C.

D.

The ratio is 34/22, or in simplest form, 17/11.

Step-by-step explanation:

We write the ratio with the number of rolls greater than three on top and the number of rolls less than or equal to 3 on bottom:

34/(56-34)

We have to subtract 34 from 56 to find out how many rolls were less than or equal to 3.

34/22

Both are divisible by 2, so we have 17/11.
