Answer:

c.The number of responses for which p\wedge q is 46.

Step-by-step explanation:

We are given that a diagram represents responses to a survey that includes statements p and q.

We have to find which statement is true in the given option.

From given diagram

p\wedge q=46

p/q=0

(p\vee q)'=20

Option A is false because p\wedge q=46.

p-q=p-p\wedge q=p-46

0=p-46

p=46

p\vee q=p+q-p\wedge q

p\vee q=46+46-46=46

Because q=46

Hence, option c is true .

Answer:c.The number of responses for which p\wedge q is 46.

Answer:

C. The number of responces p\vee q is also 46

Step-by-step explanation:

Note that:

  • p\wedge q means both p and q must hold;
  • p\vee q means either p or q must hold.

From the diagram,

  • the number of responses p\wedge q is 46;
  • the number of responces p\vee q is also 46;
  • the number of responces p\setminus q is 0;
  • the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C
