Use the given sets to find Du (En F))

U= {a, b, c, d ,...,x,y,z}
D = {h, u, m; b, l, e}
E = {h; a; m, p; e; r}
F = {t, r, a, s, h}

D u(En F)= {h, m, u, b, l, e, a, r}

The given sets are:

U= {a, b, c, d ,...,x,y,z}

D = {h, u, m; b, l, e}

E = {h; a; m, p; e; r}

F = {t, r, a, s, h}

To find Du(En F), we need to apply the following set theory formula:

Du (En F) = (Du En) U (Du F')

Here, En and F' are the complement of F with respect to U and D, respectively.

So, let's first find En:En = U ∩ E = {a, h, m, e, r}

Now, let's find F':F' = D - F = {u, m, b, l, e}Du = {h, u, m, b, l, e}

Using the formula, we get:

D u(En F) = (Du En) U (Du F')

= ({h, m, u, b, l, e} ∩ {a, h, m, e, r}) U ({h, u, m, b, l, e} ∩ {u, m, b, l, e})

= {h, m, u, b, l, e, a, r}

Answer: {h, m, u, b, l, e, a, r}
