Find the cardinal number for the following sets
A = {106, 107, 108, 109,...,142}
B= {106, 108, 110, . . ., 256}
n(A) =
+26367 Find the cardinal number for the following sets
A = {106, 107, 108, 109,...,142}
B= {106, 108, 110, . . ., 256}
Set A = { 106, 107, 108, 109,...,142 }
subtract from each element 105, we have 1, 2, 3, ... , 37
n(A) = 142 -105 = 37
Set B = { 106, 108, 110, . . ., 256 }
subtract from each element 104 we have 2, 4, 6, ... , 152
152= 2n
so
n(B) = 152/2 = 76
