3 yellow + 7 green = 10 total marbles.

The probability of picking a certain color is the number of that color over the total quantity.

Picking yellow would be 3 yellow / 10 total = 3/10

Picking green would be 7 green / 10 total = 7/10

To find the probability of doing both multiply the probability of each one by each other:

3/10 x 7/10 = 21/100

The answer would be 21/100

Answer:

A. W

Step-by-step explanation:

Because this is a rigid transformation, quadrilaterals WXYZ and ABCD are congruent. Corresponding parts of corresponding figures are congruent, so W is congruent to A and because we know the measure of angle A, you also know the angle measure of W.
