Simplify the following Boolean functions.

F$($w$,$ x$,$ y$,$ z$)=!$w$!$xz $+$ w$!$xz $+!$w$!$x$!$y$!$z $+!$w$!$xy$!$z $+!$wx$!$y$!$z $+!$wxy$!$z $+$ wxy$!$z $+$ wx$!$y$!$z $+$ w$!$x$!$y$!$z $+$ w$!$xy$!$z

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.
