HI I need help on what is the answer for this problem. Just the number 5 only. I have answer below but still so unsure. can u help me find the correct answer

Box your final answer whenever possible. 1. Page 21, No. 10 Let p, q, and r be the propositions: p : You are sick. 9 : You miss the final examination. r : You pass this subject. Express each of the following propositions as an English sentence. (a) p-q (b) ger 2. Page 22, No. 12 State the converse and contrapositive of each of the following implications. (a) If it does not rain tonight, I will go fishing tomorrow. (b) If it rains tonight, then I will stay at home. 3. Page 22, No. 16 Find the bitwise OR, bitwise AND, and bitwise XOR of each pair of bit strings. (a) 1011110, 0100001 4. Page 22, No. 20 In general, a statement involving n variables x,,X.,....*. can be denoted by P(x,,x.. ...x,) and is the value of the predicate P at the n-tuple (X,,X,....,x,) . (a) Suppose Q(x, y) denotes the statement " x=y+3 ." What are the truth values of the propositions Q(1,2) and Q(3.0)? (b) Let R(x, y,2) denote the statement " x+y=z ." What are the truth values of R(1,2,3) and R(0,0,1)? 5. Page 32, No. 2 Determine whether the following arguments are valid or not. If an argument is valid, which rule of inference is used? If not, which fallacy occurs? (a) If n is a real number such that a>1 , then n'>1 . Suppose that n'>1 . Then nal. (b) The number log, 3 is irrational if it is not the ratio of two integers. Therefore, since log. 3 cannot be written in the form : where a and b are integers, it is irrational
