Resurrecting this thread briefly to correct Mathematical error, in case anyone uses my math as a statistics lesson. I'm doing Mendelian probabilities, once something has acquired a trait, what are the chances of retaining it for a given period. I was using the form
Code:
P = 1 in (1.333^1715 x 4^1596 x 2^1419)
but that's wrong. The 'x' signs marked are wrong as these traits are not interdependent. They should be added, not moltiplied. So the equation becomes
Code:
P = 1 in (1.333^1715 + 4^1596 + 2^1419)
, and here, we get another surprise, best observed once you convert to scientific notation.
Code:
= 1.2126e214 + 7.7222e960 + 1.4506e427
When you right justify those numbers, e214 & e427 appear way down the decimal places of e960; and as scientific notation is corrected to 2 places, They disappear without trace
So the answer is 7.72e960.
