Given that P = {p: 1< p < 20}, where p is an integer and R = {r : 0 \(\leq\) r \(\leq\) 25, where r is a multiple of 4}. Find P ∩ R

{4, 8, 10, 16}

{4, 8, 12, 16}

{4, 8, 12, 16, 20}

{4, 8, 12, 16, 20, 24}

P = {p:1 < p < 20}

Then, P = { 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19}

R = { r : 0 \(\leq\) 25, r is a multiple of 4 }

Then R = { 0, 4, 8, 12, 16, 20, 24}

Thus, P ∩ R = {4, 8, 12, 16}
