Alison is playing a racing video game, in which she can pick up
items from item boxes. One of the possible items is a speed
booster, which has a 1 in 8 chance of appearing
in any item box. What is the probability that Allison will get her
first speed booster in one of her first three item boxes? Use
a TI-83, TI-83 Plus, or TI-84 calculator to find the
probability.
Round your answer to three decimal places.
