Perform the following binary subtractions of unsigned binary numbers. Convert your answer to decimal.
i) 101001012 – 010010012 ii) 110110102 – 100100112
b) Repeat the calculations above but for when the binary numbers are in two’s complement form. Comment on the results of the two methods used, noting and discrepancies.
2. Find the sums of the following unsigned hexadecimal numbers. Indicate whether or not the sum overflows an equivalent 8-bit binary result.
a) 1116 + 2216 b) 1716 + 3516 c) FA16 + CE16 d) BA16+ A1316
3. Shown below are the contents of a 16-bit resister. Determine the decimal value represented by the binary number if:
a) the binary number is unsigned b) the binary number is in two ‘s complement form.
A sequence of 10,000 five digit random numbers has been generated and an analysis of numbers indicate that there are 3075 numbers having five different digits, 4935 having a pair, 1135 having two pairs, 695 having three of a kind, 105 having a full house (three of a kind and a pair) 54 having four of a kind and one having all five of a kind. Use Poker test to determine if these random numbers are independent at = 0.0
