P=(1,2,3), Q=(3,4,5,6) dan {6,7,8} tentukan: a. P U (Q n R) b. (P U Q) n (P U R) c. P n (Q U R) d. (P n Q) U (P n R) e. (P U Q U R)

P = {1,2,3}
Q = {3,4,5,6}
R = {6,7,8}

a. P u ( Q n R)
{1,2,3} u {6}
{1,2,3,6}

b. (P u Q) n (P u R)
{1,2,3,4,5,6} n {1,2,3,6,7,8}
{1,2,3,6}

c. P n (Q u R)
{1,2,3} n {3,4,5,6,7,8}
{ }

d. (P n Q) u (P n R)
{3} u { }
{3}

e. (P u Q u R)
{ 1,2,3,4,5,6,7,8}
