Question 577893
Tiles with each of the 26 letters of the alphabet printed on them are placed in a box. If three tiles are selected from the box, with replacement, what is the probability that the tiles selected will spell the word ADD? the letters must be in order.
---
Since the drawing is made "with replacement" the probability
of drawing each letter is 1/26.
P(ADD) = (1/26)^3 = 1/17576
