Given that P={p: 1<p<20}, where p is an integer and R={r: 0≤r≤25}, where r is a multiple of 4}. Find P∩R.
- A. A. {4,8,10,16}
- B. B. {4,8,12,16}Correct
- C. C. {4, 8, 12, 16, 20}
- D. D. {4,8, 12, 16, 20, 24}
Explanation
P={2,3,4,...,19}. R={0,4,8,12,16,20,24}. Since p is an integer while r is a multiple of four, the elements in the intersection are P∩R={4,8,12,16}.
