Question

Accepted Answer

$\{3, 5, 7, 11, 13, 17, 19\}$

Answer

$\{1, 3, 5, 7, 9, 11, 13, 15, 17, 19\}$

Answer

$\{2, 3, 5, 7, 11, 13, 17, 19\}$

Answer

$\{1, 2, 3, 5, 7, 11, 13, 17, 19\}$

U={x:1≤x≤20, x∈Z}U = \{x : 1 \leq x \leq 20,\ x \in \mathbb{Z}\}U={x:1≤x≤20, x∈Z}, A={x:xA = \{x : xA={x:x বিজোড়}\}}, B={x:xB = \{x : xB={x:x মৌলিক}\}} হলে A∩B=?A \cap B = ?A∩B=?
