Question 144757
tiles with 26 letters on them in a box.  If 3 tiles are drawn from the box, with replacement. what is the probability that the tiles selected will spell the word sum?  The letters must be selected in the correct order.
=============
"With replacement" means the selections are independent.
-------
P(sum) = (1/26)^3 = 0.0000568957....
