You would multiply all of the numbers to get your answer so it would be 4*5*6*8 which would get you 960.
Answer: 960
Step-by-step explanation:
Given: Four different sets of objects contain 4, 5, 6, and 8 objects, respectively.
The number of unique combinations formed by picking one object from each set is given by :-
[tex]\text{Total unique combinations}=4\times5\times6\times8\\\\\Rightarrow\text{Total unique combinations}=960[/tex]
Hence, the number of unique combinations formed by picking one object from each set is 960.
