probability of 150 amino acids arranging in the right sequence is roughly

1 in 20 ^150 = 1 in 10 ^195

The chance probability is therefore about 1 in 10 ^195. This is also 10 ^ -195 which is 10 to the minus 195th power.

Total probability of arranging 150 amino acids in 200 M years with 1 interaction per second, not counting correct left orientation of amino acids

number of atoms in Earth = 10 ^50

number of seconds in 200 million years = 10 ^16

chance probability for 150 probability amino acids = 10 ^ -195

total probability = 10 ^50 * 10 ^16 * 10 ^ -195 = **10 ^ -129** or **10 to the minus 129th power; or 1 chance in 10 ^129 **

comparisons: number of atoms in Earth = 10 ^50

1 in 100 billion = 1 in 10^12 = **10^-12** (= 10 to the minus 12)

1 in 100 billion x 100 billion = 1 in 10^12 x 10^12 = **10^-24, which is much less than 10 ^ -129 **
