a is the set of integers greater than or equal to -8 and less than or equal to - 1
b={-21, 20, 21, 25, 29}
(a) find the cardinalities of a and b.
n (a) =
n(b) =

Step-by-step explanation:

The cardinality is the number of elements in the set.

We need to list the element of the first set A, the set of integers greater than or equal to -8 and less than or equal to - 1

A={-8,-7,-6,-5,-4,-3,-2,-1}

The number of elements in this set is 8.

The second set is B={-21, 20, 21, 25, 29}.

The number of elements in this set is 5

answer: 193

explanation:

200-7 = 193
