Thirty percent of all customers who enter a store will make a purchase. suppose that six customers enter the store and that these customers make independent purchase decisions. (1) use the binomial formula to calculate the probability that exactly five customers make a purchase. (round your answer to 4 decimal places.) probability (2) use the binomial formula to calculate the probability that at least three customers make a purchase. (round your answer to 4 decimal places.) probability (3) use the binomial formula to calculate the probability that two or fewer customers make a purchase. (round your answer to 4 decimal places.) probability (4) use the binomial formula to calculate the probability that at least one customer makes a purchase. (round your answer to 4 decimal places.) probability

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.
