Mary is at the basketball court. She is practicing her free throws by taking three shots at a time. She would consider this one "set" of shots. She is also not confident in her abilities, and estimates her chance of missing any single shot to be 0.45.

For any given set of shots, calculate the probability that Mary will score at least 2 points (1 point is awarded for each successful shot). Give your answer as a decimal to 4 decimal places.
