The correct answer is: 253

To find the decimal representation of the binary number 1111 1101, each digit of the binary number corresponds to a power of 2, starting from the rightmost digit, which is 2^0. In this case, the binary number can be broken down as follows: - The far-right digit is 1, which represents 2^0 (1). - The next digit is also 1, representing 2^1 (2). - The next is 0, representing 2^2 (0). - The following digit is 1, representing 2^3 (8). - Next is another 1, representing 2^4 (16). - Another 1 follows, representing 2^5 (32). - Next is another 1, representing 2^6 (64). - The leftmost digit is also 1, which represents 2^7 (128). Now, adding these values together, we calculate: 128 (for 2^7) + 64 (for 2^6) + 32 (for 2^5) + 16 (for 2^4) + 8 (for 2^3) + 0 (for 2^2)
