Nicole was telling the truth; Jessica broke the monitor.

If only 1 of the 4 was telling the truth, that means that the other 3 were lying.  By using deductive reasoning, one would conclude that the only possibility with the presented facts is that Jessica was lying when she said, “It wasn’t me,” Sandy was lying when she said, “It was Nicole,” and Melissa also lied when she said, “No, it was Sandy.”  This leaves Nicole as the truth-teller, revealing Jessica as the culprit, having stated a direct lie when she said “It wasn’t me!”

There is an 85% probability that Mary dropped a penny.  There are two (and only two) combinations of 50 coins that will add up to $1.00.  These are:

40 Pennies, 2 Dimes, 8 Nickels, and
45 Pennies, 2 Dimes, 2 Nickels, 1 Quarter

With the first scenario alone, there would be a 80% probability, and the second scenario alone equates a 90% probability, respectfully.  But because we don’t know which she had, the probability is the average of the two, or 85%.
