A consumer organization estimates that 32% of the households in a particular community have one television set, 38% have two set s, and 16% have three or more sets. If two households are chosen at random, what is the probability that at least one has one or more television sets

Answer:
If two households are chosen at random, the probability that at least one has one or more television sets is equal to 0.9804 or (98.04%)
Step-by-step explanation:
32% of the households have one television set, 16% have three or more sets Then 100% - ( 32%+ 38% + 16% ) = 14% of households does not have any television set
the probability that both of the two randomly chosen households does not have any television set is 0.14×0.14 =0.0196
If two households are chosen at random, the probability that at least one has one or more television sets is equal to
1 - (the probability that both of the two randomly chosen households does not have any television set) = 1- 0.0196 = 0.9804 (98.04%)

I think that I am right and also think this will helpful to you.....
1/4 of 20 is 5.. and 5/10, 3/6, 2/4, 6/12 are all equal to 1/2
So, let the one angle be
As we know that,
Sum of all interior angles of a quadrilateral =
So let's sum up the given angles,
Hence,
So, First angle
Second angle
