Question

Write down the union and intersection of the following pairs of sets: [2+4] (i) X = {a, b, c, d, e} Y = {c, e, f, g} (ii) P = {multiple of 2 between 9 and 21} Q = {multiple of 3 between 10 and 20}

Answer 1

Answer:

{a,b,c,d,e}U{c,e,f,g} = {a,b,c,d,e,f,g}

{a,b,c,d,e} intersection {c,e,f,g} ={c,e}

I hope it will help u☺️
