A box contains 6 yellow, 3 red, 5 green, and 7 blue colored pencils. A colored pencil is chosen at random, replaced, then another is chosen. What is the probability of choosing blue then a yellow colored pencil? pls help i will give brainliest

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
