The probability mass function for the number \( x \) of coding errors found in 1000 randomly selected lines of computer code is given by \[ x: 0, 1, 2, 3, 4 \] \[ p(x): 0.08, 0.15, 0.45, 0.27, 0.05 \] a. Calculate the **mean** number of coding errors for all such blocks of 1000 lines of code. b. Calculate the variance and standard deviation of \( x \).
