Chapter 13: Q 22. (page 847)

How many are in A or B or C?

Short Answer

Expert verified

There are 64 in A or B or C.

n (A \cup B \cup C) = 64

Step by step solution

Step 1. Given information

Step 2. Calculation

$From the venn diagram : n (A) = (15 + 3 + 5 + 2) = 25 n (B) = (10 + 3 + 5 + 2) = 20 n (C) = (15 + 2 + 5 + 2) = 24 n (A \cap B \cap C) = 5 Using the formula : n (A \cup B \cup C) = n (A) + n (B) + n (C) - n (A \cap B \cap C) n (A \cup B \cup C) = 25 + 20 + 24 - 5 n (A \cup B \cup C) = 64$
