The combinations formula is nCr =

n = complete value set r = desired goal
to find combinations we find all combos for 5,6,7,8,and 9 and add them together.
which come out as 126, 84, 36, 9 and 1
Therefore there are 256 combinations

Answer: c.A is the set of rational numbers
Step-by-step explanation:
B ⊆ A means that every element of B is an element of A
B = { -13 , -9 , -7 , - 3 }
The element of B are negative integers , this mean that the element of A must also be integers therefore :
Option a is correct.
Option b is also correct
Rational numbers are numbers that can be express in the form a/b , examples are : 1/2 , 3/ 4 , 5/6 ...
clearly , this does not necessarily define A , so option c is the odd one out
