Probability: Marbles in a jar |
2008-09-22 |
|
Andrea pose la question :
Suppose you have a jar containing 100 red marbles and 100 white marbles.
A) If you draw 5 marbles in a row, throwing each marble across as you
draw it, what is the probability that at least one of them was red?
B) If you draw 101 marbles in a row, throwing each one across the room
as you draw it, now what is the probability that at least one of them was
red?
