According to a survey of american households, the probability that the residents own two cars if annual household income is over $50,000 is 80%. of the households surveyed, 60% had incomes over $50,000 and 70% had two cars. the probability that the residents of a household do not own two cars and have an income over $50,000 a year is

12%

Step-by-step explanation:

The probability that the residents of a household do not own two cars and have an income over $50,000 a year is 100% subtracted by the probability of owning two cars and having an income over $50,000(P(2∩50+) and the probability of not having an income over $50,000 (P(50-))

Therefore, the probability that the residents of a household do not own two cars and have an income over $50,000 a year is 12%

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
