HH: "The odds of picking at random the four letters F, O, U, R in this sentence and in that order are one out of one hundred twenty-seven thousand seven hundred seventy-six." If the probability is 4*11*6*9/132^4 ... EA: ... aren't the odds 4*11*6*9/(132*131*130*129) ? [brackets added] OK. Second attempt: "The odds of randomly picking four letters from this statement and having them be F, O, U, and R, are two out of two hundred nineteen thousand six hundred eighty-seven." Letter count = 132. F count = 5. O count = 11. U count = 6. R count = 8. 5*11*6*8/(132*131*130*129) = 2/219687
