Suppose you have a 10 by 10 grid of marbles. There is a 50% chance for each marble that the color is RED and a 50% change the color is BLUE.

What is the probability, given a random configuration, that there will be a 5x5 grid of RED marbles. The 5x5 REDs can be anywhere on the grid.

We have been asked to investigate two flights, AA flight and U A flight. Both flights are at 33,000 feet, and the flight paths intersect directly over city of Frada Heights. A committee of concerned citizens has petitioned the City to investigate the possible danger of a collision of these two flights.

On the day we checked, we found that at 1:30 PM , AA was 32 nautical miles from Frada Heights, approaching it on a heading of 171ø at a rate of 405 knots. At the same time, United was 44 nautical miles from Frada Heights and was approaching it on a heading of 81ø at a rate of 465 knots.

The DPS has asked us to determine how fast the planes were approaching each other (i.e., how fast the distance between them was decreasing) at that time. The DPS would also like to know whether the flights would have violated the FAA's minimum separation requirement of 5 nautical miles. we would like to determine how close the planes actually get to each other.
