\n" ); document.write( "We'll assume each coin is a fair coin. This means each coin has equal probability of getting heads or tails. That probability being 1/2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since each coin toss is independent of one another, the probability of getting all tails is (1/2)^8 = 1/256\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The probability of at least one head showing up would then be 1 - (1/256) = 255/256
\n" ); document.write( "This works because we either get all tails, or at least one head shows up. The term \"at least\" means \"that amount or more\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 255/256
