$(1$ point$)$ Consider the hex strings $A=0e17b6c017701cbc4$ and $B=00263a492448247be.$

a$)$ What is $Ao+B$ in hexadecimal? Please give your answer a leading $0x$ and use lowercase letters only. Make sure you use exactly $16$ hex digits $($which may involve tvping in leading zeros$).$ hexadecimal:

b$)$ Suppose that A was generated uniformly at random from all $8$ byte strings. What is the probability that the second binary digit of $A$ is $1?$

c$)$ Suppose that A was generated uniformly at random from all $8$ byte strings. What is the probability that the second binary digit of $Ao+B$ is $1?$
