You want to simulate a coin flipping or other Boolean (true/false) event in which there is a 50% chance of either outcome.

Use the `randRange( )`

method to generate an
integer that is either 0 or 1 and then correlate each possible answer
with one of the desired results.

You can use the `randRange( )`

method from
Recipe 5.7 to generate a random integer in
the specified range. To relate this result to an event that has two
possible states, such as a coin flip (heads or tails) or a Boolean
condition (true or false), treat each random integer as representing
one of the possible states. By convention, programmers use 0 to
represent one state (such as “off”)
and 1 to represent the opposite state (such as
“on”), although you can use 1 and 2
if you prefer.

For example, here is how you could simulate a coin flip:

#include "Math.as" function coinFlip ( ) { flip = Math.randRange(0, 1); if (flip == 0) { return "heads"; } else { return "tails"; } } // Example usage: trace ("The result of the coin flip was " + coinFlip( ));

Here, we write a function that tests our ```
coinFlip(
)
```

routine to see if it is reasonably even-handed. Do you
expect a perfect 50/50 distribution regardless of the number of coin
flips? Test it and see.

#include "Math.as" function testCoinFlip (numFlips) { // We'll count how many of each result occurs. Initialize them to 0. var heads = 0; var tails = 0; // Repeat the processtimes and keep tabs on the results. for (var ...`numFlips`
