3. In a little league playoff game the series is a best of 5 wherethe first team to win 3 games wins the series.If team A has a 70% chance of winning and team B has a 30% chance of winning any game.

Describe and design simulationsthat could be used by statisticians to (i) Determine theprobability that Team A will win the seriesand (ii) Determine theexpected number of games that the series will go to.

You don't need to do the simulation but you can give an example.
