Save this quantity as the variable netflix$\_$subs$6$ in your Colab notebook. $($This should be a value between $0$ and $1.)$ You may use previously defined functions to solve this problem.

Previous functions:

def subscriber$\_$vals$($x$\_0,$ k$)$:

P $=$ np$.$array$([[0\mathrm{.}7,0\mathrm{.}2],$

$[0\mathrm{.}3,0\mathrm{.}8]])$

x $=$ x$\_0$

for $\_$ in range$($k$)$:

x $=$ np$.$dot$($P$,$ x$)$

return x
