Find the cardinal number for the following sets.
A = {101, 102, 103, 104 ,...,127 }
B ={101 , 103 , 105 , ..., 301 }
n(A) =
n(B) =
The number of elements in set A is found by the formula: largest - smallest + 1
n(A) = 127 - 101 + 1 = 27
The number of elements in set B is found by the formula: (largest - smallest) / 2 + 1
n(B) = (301 - 101) / 2 + 1 = 101
