Atelevision poll of 151 persons found that 68 watched ""law and disorder""; 61 watched ""25""; 52 watched ""the tenors""; 16 watched both ""law and disorder"" and ""25""; 25 watched both ""law and disorder"" and ""the tenors""; 19 watched both ""25 "" and ""the tenors""; and 26 watched none of these shows. how many persons watched all three shows?

The answer is 4.

Explanation:

If we are trying to know how many people watched the show, we have to substract 26 that watched none of the shows, so:

151-26=125

Now that we know the numbers, the easiest way to know the "x" is with a Venn Diagram. But the equation is also quiet simple.

125(total people)-68(Law and Disorder)-61(25)-52(The Tenors)+16(Law and Disorder"" and ""25"")+25("Law and Disorder"" and ""The Tenors")+19(""25 "" and ""The Tenors"") = 4

That is: 15-68-61-52+16+25+19=4

4 people watch all three shows.
