Hi,

If three coins are tossed simultaneously, the following are possible:

{HHH, HHT, HTH, TTH, TTT, THH, THT, HTT}

In this case n(S) = 8.

It can be written in smaller cases.

If I say, 10 coins are tossed simultaneously, how do I calculate the number of possibilities? Is there a formula to do the same?

Thanks

Ashwin
