$1.(10$ pts$.)$ Using IEEE $754$ floating point representation for $32-$bit floating point values, match the following floating$-$point values with their binary representation:

$2.(10$ pts $.)$ Consider the following C program. Assume that all functions complete successfully. Complete the Process Model, given that the process id's $($pids$)$ are as shown for each process created. Fill in the boxes for each variable, p$1$ and p$2,$ showing their final values in each process.
