1. Let A = {al(a>0 A (a <20) ^ a e: B = {bb > 15 Abs 20 Ab E Z} C = {clc 20) (cs 100) ACE D = {dd e z+ and d2 < 30} a. Show set A b. Show set B C. Show set D d. Compute AUB e. What is the value of|A|? f. Compute BNC g. Compute A - B
{al(a > A(a <20) ^ a ZA a is divisible by 5} = {bb 15 Ab S 20 Ab E Z} = {clc 20)^(CS100) ACE Z Ac is odd} {dd ezt and d? <30)
A = {ala >0 A (a <20) AaEZA a is divisible by 5), B = {b|b 15 Ab S 20 Ab E Z} C = {cl(20)^(cs 100) ACEZAc is odd} D = {d d e z+ and d<30)
