Answer:

Step-by-step explanation:

Given

No of People who can speak English is n(E)=68

No of People who can speak French is n(F)=45

No of People who can speak Spanish is n(S)=42

No of People who can speak both English and French n\left ( E\cap F\right )=27

No of People who can speak both English and Spanish n\left ( E\cap S\right )=25

No of People who can speak both French and Spanish n\left ( F\cap S\right )=16

No of people who can speak all languages is n\left ( E\cap F\cap S\right )=9

no of People who can Speak at least one Language is

n\left ( E\cup F\cup S\right )=n\left ( E\right )+n\left ( F\right )+n\left ( S\right )-n\left ( E\cap F\right )-n\left ( E\cap S\right )-n\left ( F\cap S\right )+n\left ( E\cap F\cap S\right )

n\left ( E\cup F\cup S\right )=68+45+42-27-25-16+9=96

Probability that Randomly selected can speak at least 1 of these languages

P=\frac{96}{100}=0.96

So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M. 

Now you will connect the line M and Z.

Thats it! I hope this helped!! :)
