PLEASE EXPLAIN HOW TO DO THIS!! I COMPLETELY FORGOT ☠️-

A bag contains 86 marbles, some of which are black and some of which are white. If the probability of selecting a black marble is 33/43 find:

A) The number of black marbles

B) The number of white marbles

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
