The number of possible incomes is \"2%5E40\" which is 1,099,511,627,776. There is 41 incomes that does not favor the probability we want to get. So 1,099,511,627,776-41=1,099,511,627,735. Therefore, the probability is \"1099511627735%2F1099511627776\" which is approx. 99.9999999962711% \n" ); document.write( "
