Answer:
D
Step-by-step explanation:
Hello!
To find the probability of two events, you need to multiply the probability of all the events that make the compound event. In this case, we need to multiply the probability of selecting urn 1 and selecting a white marble from urn 1.
First, we have two urns, so we have a 1/2 chance of selecting urn 1.
Next, we have 16 total marbles in urn 1. If we have 5 white marbles, this gives us 5/16.
Finally, we multiply the probabilities. 1/2(5/16)=5/32.
Our final probability is 5/32, or about 16%.
I hope this helps!

Answer:
12/25
Step-by-step explanation:
The problem tells us that we need to use 25 equally sized stones to make a 12 feet long path. As the stones must be equally sized, you have to divide 12 by 25 to distribute the feet length equally. Therefore, 12 divided by 25 is just rewritten as 12/25 feet long.
