coin toss programme for MS Excel

hey,
I need help writing a code for this to work through the macros in excel,
if anyone can do it then please help me!!!
Thanks

Four (04) coins are tossed simultaneously (ie at the same time) and results in either a
HEADS or a TAILS in each coin. i want to simulate the tossing of the four coins 100,000 times and show that the probability of each possible event (ie a HEADS, HEADS, HEADS AND HEADS, a TAILS, TAILS, TAILS and TAILS in all four coins or ANY OTHER POSSIBLE COMBINATION (ie HEADS,
HEADS, HEADS and TAILS etc)) approaches the theoretical probability as the number of
tosses increase.
