For each toss the probability of heads is expected to be $\"1%2F2\"$ .
\n" ); document.write( "The outcome of each toss is independent of the outcome of the other tosses, so the probability of getting 100 heads in 100 tosses of a coin is
\n" ); document.write( " $\"%281%2F2%29%5E100=1%2F2%5E100=1%2F2%5E%2810%2A10%29=1%2F%282%5E10%29%5E10=1%2F1024%5E10\"$ .
\n" ); document.write( "I really do not want to accurately calculate $\"1024%5E10\"$ or $\"1%2F1024%5E10\"$ .
\n" ); document.write( " $\"1%2F1024%5E10\"$ is less than $\"1%2F1000%5E10=1%2F%2810%5E3%29%5E10=1%2F10%5E30\"$ ,
\n" ); document.write( "which could be expressed as 1 in $\"10%5E30\"$ , or
\n" ); document.write( "1 in 1,000,000,000,000,000,000,000,000,000,000. \n" ); document.write( "
