Let A and B be two sets containing 2 elements and 4 elements respectively. The number of subsets of `AxxB` having 3 or more elements is (1) 220 (2) 219 (3) 211 (4) 256

Explanation

To solve the problem, we need to find the number of subsets of the Cartesian product \( A \times B \) that contain 3 or more elements. Let’s break it down step by step.

### Step 1: Determine the sizes of sets A and B
Set \( A \) has 2 elements, and set \( B \) has 4 elements.

### Step 2: Calculate the size of the Cartesian product \( A \times B \)
The Cartesian product \( A \times B \) consists of all possible ordered pairs where the first element is from set \( A \) and the second element is from set \( B \).
