Question

$n(a) = square$
$n(a\cap c) = square$
$n(a\cap b\cap c^{c}) = square$

Explanation:

Step1: Sum all regions in set A

$n(A) = 13 + 7 + 1 + 8$

Step2: Calculate total for $n(A)$

$n(A) = 29$

Step3: Sum regions in A∩C

$n(A \cap C) = 8 + 1$

Step4: Calculate total for $n(A \cap C)$

$n(A \cap C) = 9$

Step5: Identify region for $A∩B∩C^c$

This is the part of A∩B not in C: $7$

Answer:

$n(A) = 29$
$n(A \cap C) = 9$
$n(A \cap B \cap C^c) = 7$
