Each of k urns contains m white and n black balls. A ball is randomly chosen from urn 1 and transferred to urn 2, then a ball is randomly chosen from urn 2 and transferred to urn 3, etc. Finally, a ball is randomly chosen from urn k. What is the probability that the ball chosen from the kth urn is white

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

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
