A number cube labeled 1 throught 6 is rolled three times. one group of three digits represents one set of rolling the cube three times. The experiment is repeated 20 times and the results are shown below: 443,654,553,646,121,334,652,426,152,544,136,555,314,315,461,123,646,163,345,363. Event E represents rolling exactly two even numbers what is P(E) ? write the answer as a fraction in lowest terms.
