Let P be a point outside the circle such that triangle LMP has legs coincident with chords MW and LK (i.e. M, W, and P are colinear, and L, K, and P are colinear). By the intersecting secants theorem,

The angles in any triangle add to 180 degrees in measure, and
and
, so that


4/9 (4 out of 9) because you add them all together then count the number of blue marbles then since you put back the first marble, the dominator is still the same
the dot plot, because box plot only shows the 5 number summary and histograms show ratios
The answer is 0.4 or 0.40
