Question

use the accompanying venn diagram, which shows the cardinality of each region, to answer the question below.
how many elements belong to set b or set c, but not set a?
there are \\(\square\\) elements that belong to set b or set c, but not set a.

Explanation:

Step1: Identify regions for B or C, not A

Regions in B or C but not A: B only (7), C only (9), and B∩C not A (3).

Step2: Sum the regions

Sum: \( 7 + 9 + 3 = 19 \).

Answer:

19
