Given the following code, which parameters are passed by value and which are passed by reference?

def main$()$:

$$ nbrlist $=[10,20,30]$

$$ x $=0\mathrm{.}5$

$$ y $=1\mathrm{.}0$

$$ processList$($nbrlist$,$ x$,$ y$)$

$$

def processList$($list$,$ a$,$ b$)$:

$$a $=2\mathrm{.}0$

$$for i in range$($len$($list$))$:

$$list$[$i$]=$ list$[$i$]*$ b

$$

# The entry point for program execution
