Answer:
The cardinal number is 5.
Step-by-step explanation:
The cardinal number is the number of elements present in a set.
The question will be read as : {x is such that x belongs to (or an element of) a whole number, x is less than 5} .
A={0,1,2,3,4}
(0 included because x is a whole number).
So, the number of elements is 5.
