Question

for my exams don't fake plz
5 mark step by step plz
If P ={ x : x ∈ W and 0 < x < 10}, Q ={ x : x = 2n +1, n ∈W and n < 5 }
and R = { 2, 3, 5, 7, 11, 13 }, then verify P – (Q∩ R) = (P – Q) ∪ (P – R)
30 points

Answer 1

Answer:

P={1,2,3,4,5,6,7,8,9,} ,Q={1,3,5,7,9},R={2,3,5,7,11,13}

Step-by-step explanation:

(Q intersection R)={3,5,7}

P - (Q intersection R)={1,2,4,6,8,9}

(P - Q)={2,4,6,8} ,(P - R)={1,4,6,8,9}

(P - Q) U (P - R) ={1,2,4,6,8,9}

P - (Q intersection R) = (P - Q) U ( P - R)

Both are equal

I hope you are understand it and if u like it please give me a BRAINLIEST BRAINLIEST
