Simplify the following Boolean functions.

F$($w$,$ x$,$ y$,$ z$)=!$w$!$x$!$yz $+!$w$!$xyz $+!$wx$!$y$!$z $+$ wx$!$y$!$z $+$ xy$!$z $+$ w$!$x$!$yz $+$ w$!$xyz

F$($w$,$ x$,$ y$,$ z$)=\_\_\_\_\_$answer$\_\_\_\_\_\_\_$

$*$Please do not include $"$F$($w$,$ x$,$ y$,$ z$)="$ in your solution. Add a single space between variables and operators.
