Answer:

n(B) = 1350

Step-by-step explanation:

Using Venn sets, we have that:

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

Three values are given in the exercise.

The other is n(B), which we have to find. So

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

$2290 = 1300 + n(B) - 360$

$940 + n(B) = 2290$

$n(B) = 2290 - 940 = 1350$

n(B) = 1350
