The answer is A) 1:2, because there are 80 blue marbles and 40 red marbles, (for a total of 120 marbles) and the ratio 40:80 simplifies down to 1:2.
The total number of elements in either Set A or Set B. is 124.
<h3>How can the number of
set in mathematics be calculated?</h3>
Since Set A contains 62 elements
Set B contains 94 elements
Then total element= (62+94)=156
But the Sets A and B have 32 elements
Therefore, total number of elements in either Set A or Set B. is (156-32)= 124.
