You have two jars, 50 red marbles and 50 blue marbles. A jar
will be picked at random, and then a marble will be picked
from the jar. Placing all of the marbles in the jars, how
can you maximize the chances of a red marble being picked?
What are the exact odds of getting a red marble using your
scheme?

Answer Posted / john bevan

So long as you have at least 1 red marble in each jar you
have 100% chance of a red marble being picked. The question
only states that the jar is selected at random.
