You will be given several sets and asked to determine their cardinalities.
A = { x {0,1}6 | x[2..4] = 010 } B = { f: {1,2,3,4} {0,1} } C = { f: {1,2,3} {1,2,3,4} | f is one to one } D = { x {0,1}3 {0,1}5 | #0(x) = #1(x)+1 } E = { n {10,11,...,29} | n 1 mod 3 }
The answer is |A| = 8, |B| = 16, |C| = 24, |D| = 13, |E| = 7. Please show the process.
