$(1$ point$)$ Consider the hex strings $A=00980f06c2c48a607$ and $B=06bf107f9e76b601f.$

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 typing in leading zeros$).$

hexadecimal:

b$)$ Suppose that A was qenerated 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 $1?$
