7. In a certain neighborhood of 100 families, 60 get their news from TV, 54 from the local paper, and 20 from both sources. If a family is selected at random, what is the probability that this family does not use any one of these sources for the news?

If a family is selected at random, the probability that this family does not get news from either TV or from local paper = 6% or 6/100

Explanation:

From the given data:

The total number= 100

Families that got their news from TV =60

Families that got their news from local paper= 54

Families that got their news from both TV and local paper= 20

The probability that family does not use any one of these sources for the news = 1 - probability of the event

If a family is selected at random, the probability that this family does not use any one of these sources for the news = 1 - (The probability that a selected family get news from either TV or from local paper)

If a family is selected at random, the probability that this family does not use any one of these sources for the news = 1 - (60/100 + 54/100 -20/100)

= 1 - (94/100)

= 1 - 0.94

=0.06

If a family is selected at random, the probability that this family does not get news from either TV or from local paper = 6% or 6/100

answer; ///(c) i believe that the correct answer is ethnic relations bear many similarities across different global; good luck

the correct answer is modern american cars are not available due to trade restrictions.

trade between cuba and the united states have serious restrictions. the u.s. imposed an economic embargo on cuba, that among other things means that modern american cars are not available due to trade restrictions.

in response to some governmental actions of the authorities from cuba, president john f. kennedy proclaimed an embargo on trade between both countries in february 1962. the trade embargo remains active until this day and was implemented directly by the departments of commerce and the department of treasury.

in president trump’s administration, there is a national security presidential memorandum that "strengthens the policy of the u. s.", affecting trade with cuba.
