The Venn diagram shows the results of two events resulting from rolling a number cube.

Option B.

Step-by-step explanation:

From the given venn diagram it is clear that

Since the intersection of A and B is non-empty, therefore by conditional probability

Therefore, the correct option is B.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
