This is a clear image of my question the question is Below is a tree diagram for an event with three possible outcomes. A, B and c. This event occurs twice.

What is the probability of outcome B occurring at least once?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x
