A survey conducted by the Harris polling organization discovered that 63% of all Americans are overweight. Suppose that 30 randomly selected Americans are weighed. a) Find the probability that 18 of the 30 people are overweight.
b) Find the probability that at least one of the 30 people are overweight.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
