(30 points of my grade) Emil would like to estimate the probability of 2 or more heads coming up in 3 coin flips.

To do this, he has a computer randomly select 0 or 1 three times, with 0 representing heads and 1 representing tails. The results of 12 trials are shown in the table.

111 011 000 010 100 111
010 111 111 101 000 111
What is Emil's estimated probability, based on this simulation?

Enter your answer as a fraction, in simplified form, in the box.
